vegan dinner party

There are meals you make because dinner is needed. And then there are meals like these Spicy Tomato Sushi Rolls with Forbidden Rice — the kind that arrive on the board as sixteen dramatic, jewel-like rounds of deep purple-black forbidden rice wrapped around a vivid filling of spicy marinated tomato, creamy avocado, and fresh greens, so visually extraordinary that people stop and stare before they reach for one. This is that meal. The one that looks like it belongs on the table of a fine dining restaurant and is made entirely in your own kitchen. The one that proves plant-based cooking is not just nourishing but genuinely, breathtakingly beautiful.

These inside-out sushi rolls use cooked forbidden rice — the striking deep purple-black short grain rice that turns the entire roll into something visually dramatic — seasoned with rice vinegar, sugar, and salt in the traditional sushi rice manner, then rolled outside-in around a filling of roma tomatoes marinated in sesame oil, soy sauce, and chili until they take on a rich, deeply savory, slightly spicy character, with layers of ripe avocado and fresh greens that add creaminess and brightness to every single piece.

What makes these rolls so outstanding is the forbidden rice — its natural deep purple-black pigment from anthocyanins produces a color so dramatic against the vivid red tomato and green avocado filling that each sliced roll is a genuinely beautiful thing, making this one of the most visually impressive plant-based dishes in the entire collection.

This recipe is 100% vegan, naturally gluten-free when made with tamari, ready in about 60 minutes, and absolutely magnificent arranged on a board and served with pickled ginger, wasabi, and a small bowl of soy sauce alongside.

Recipe Information

Ingredients

For the Forbidden Rice

• 1½ cups (300g) black forbidden rice
• 2 cups (480ml) water
• 3 tbsp rice vinegar
• 1 tbsp sugar
• 1 tsp salt

For the Spicy Marinated Tomato Filling

• 4 roma tomatoes, deseeded and cut into long strips
• 2 tbsp soy sauce or tamari
• 1 tbsp sesame oil
• 1 tbsp rice vinegar
• 1 tsp sriracha or chili garlic sauce
• 1 tsp maple syrup
• ½ tsp smoked paprika

For the Roll Filling

• 2 ripe avocados, sliced into long strips
• 1 cup (30g) fresh spinach, watercress, or microgreens
• ½ cucumber, cut into thin matchsticks
• 4 nori sheets

For Serving

• Soy sauce or tamari for dipping
• Pickled ginger
• Wasabi paste
• Sesame seeds scattered over the finished rolls
• Edible flowers for garnish (optional — as shown)

Instructions

1. Cook the forbidden rice. Rinse the black rice thoroughly until the water runs less purple. Combine with 2 cups of water in a saucepan, bring to a boil, reduce to the lowest simmer, cover, and cook for 30–35 minutes until the water is absorbed and the rice is tender. Remove from heat and let steam covered for 10 minutes. Transfer to a wide bowl.
2. Season the rice. In a small bowl dissolve the sugar and salt in the rice vinegar by whisking or warming briefly. Pour over the warm rice and fold through gently with a rice paddle or spatula until evenly seasoned. Fan the rice gently as you fold to help it cool — seasoned sushi rice should be used at body temperature, not hot. Cover with a damp towel while preparing the filling.
3. Marinate the tomatoes. Combine the soy sauce, sesame oil, rice vinegar, sriracha, maple syrup, and smoked paprika in a shallow dish. Add the tomato strips and toss gently to coat. Marinate for 15 minutes — the tomatoes absorb the marinade and take on a deeply savory, spicy character that replicates the umami depth of traditional sushi fillings.
4. Prepare the rolling station. Place a bamboo sushi mat on a clean surface and cover with plastic wrap — this prevents the rice from sticking to the mat during inside-out rolling. Fill a small bowl with water for wetting your hands.
5. Build the inside-out roll. Place a sheet of nori shiny-side down on the plastic-wrapped mat. With wet hands, spread a thin, even layer of forbidden rice over the entire nori sheet, pressing gently to adhere. The rice layer should be approximately 5mm thick — thin enough to roll cleanly, thick enough to hold the filling.
6. Flip the nori. Carefully flip the entire nori sheet rice-side down onto the plastic wrap so the rice is now on the outside and the nori is facing up. This is the inside-out configuration that puts the dramatic black rice on the exterior.
7. Add the filling. Arrange a line of marinated tomato strips, avocado slices, fresh greens, and cucumber along the bottom third of the now-upward-facing nori.
8. Roll tightly. Using the mat, lift the bottom edge and roll firmly and tightly over the filling, pressing as you go to maintain a compact, even cylinder. Continue rolling to the far edge, pressing firmly at the end to seal.
9. Slice and serve. Using a very sharp knife dipped in water and wiped between each cut, slice each roll into 8 even pieces. Arrange on a board, scatter sesame seeds over the top, add edible flowers if using, and serve immediately with soy sauce, pickled ginger, and wasabi alongside.

Pro Tips

• Wet your hands thoroughly before handling the rice — forbidden rice is stickier than white sushi rice and sticks to dry hands, tearing the nori and disrupting the even layer.
• Use the rice at body temperature — hot rice tears the nori; cold rice does not adhere properly. Body temperature is the traditional sushi rice standard and produces the cleanest rolling experience.
• Cover the mat with plastic wrap before rolling — this is essential for inside-out rolls and prevents the rice from sticking to the mat surface.
• Use a very sharp knife and wipe between every cut — forbidden rice is stickier than white rice and requires a clean, sharp blade to slice without dragging the filling out of the roll.
• Pat the marinated tomato strips gently dry before placing in the roll — excess marinade makes the roll too wet and can cause it to fall apart during slicing.

Why Forbidden Rice Makes This Dish So Spectacular

Forbidden rice — also known as black rice or purple rice — gets its dramatic deep purple-black color from anthocyanins, the same group of pigments that give blueberries, purple cabbage, and acai their distinctive colors. These pigments are powerful antioxidants, making forbidden rice not only visually extraordinary but also one of the most antioxidant-rich rice varieties available.

The name “forbidden” derives from ancient China, where black rice was so prized for its nutritional value and rarity that it was reserved exclusively for the Emperor and the imperial court — commoners who grew or consumed it faced severe punishment. Today it is widely available and its dramatic color, slightly nutty flavor, and firm, slightly chewy texture make it one of the most rewarding ingredients in plant-based cooking.

When used as the exterior rice in inside-out sushi rolls, the deep purple-black color creates a visual contrast against any filling that is genuinely dramatic — particularly against the vivid red of spicy marinated tomato and the bright green of avocado, producing rolls that look almost too beautiful to eat.

Flavor Variations

• Mango and Avocado Forbidden Rice Rolls: Replace the spicy tomato filling with fresh mango strips and avocado for a sweeter, more tropical version with an equally beautiful color contrast.
• Crispy Tofu Forbidden Rice Rolls: Add thin strips of sesame-crusted crispy tofu alongside the tomato filling for extra protein and texture.
• Cucumber and Cream Cheese Rolls: Fill with vegan cream cheese and cucumber for a simpler, more accessible version that is particularly appealing as a first sushi-making project.

Nutritional Highlights (Per Serving — 8 pieces)

Storage

• Best fresh: These rolls are at their best within 1 hour of making — the rice begins to harden and the nori softens during storage.
• Refrigerator: Store wrapped tightly in plastic wrap for up to 1 day. The texture will be slightly different but the flavor remains excellent.
• Do not freeze: Sushi rolls do not freeze well — the rice becomes hard and grainy and the fillings lose their texture entirely.
• Components: The marinated tomato filling and seasoned rice can be made ahead and stored separately — assemble the rolls fresh when ready to serve.

Frequently Asked Questions

Where do I find forbidden rice?

Black forbidden rice is available at Asian grocery stores, health food stores, and increasingly at mainstream supermarkets in the rice or health food aisle. It is also widely available online.

Can I use regular sushi rice instead of forbidden rice?

Yes — regular short grain white sushi rice works with the same technique and filling for a more classic visual result. The forbidden rice is specifically chosen for its dramatic color and slightly nuttier flavor.

Do I need a bamboo sushi mat?

A bamboo sushi mat makes rolling significantly easier and produces more even, professional rolls. A clean kitchen towel covered with plastic wrap can be used as a substitute, though the rolls may be slightly less even.
