What is a Sushi Sandwich Triangle?
A sushi sandwich triangle (or onigirazu) is a layered sushi wrap that’s shaped like a sandwich instead of the usual sushi roll. It usually consists of rice, fillings, and seaweed, but this recipe takes a crispy twist by adding rice paper as the outside layer. The result is a crispy, pan-fried sushi sandwich that combines the best of sushi and a crunchy rice paper wrap.

How to Make California Roll Rice Paper Sushi Sandwich (Onigirazu)
Prepare the Rice and Crab Filling
Rinse the sushi rice thoroughly, then cook it in a pot or rice cooker according to package instructions. Once cooked, mix in rice wine vinegar and a pinch of salt for that classic sushi rice flavor. Let it cool slightly.
Shred the imitation crab sticks using your hands, pulling them apart like string cheese. Mix in sriracha, kewpie mayo, and a pinch of salt until well combined.
Assemble the Sushi Sandwich Triangle
Lightly oil a cutting board to prevent sticking. Rehydrate one square sheet of rice paper in warm water and place it on the board. Repeat with a second sheet, layering it on top. Place a nori sheet over the rice paper.
Using scissors, cut a single slit from the center of the bottom edge to the middle. This will help with folding.
On the bottom left section, spread about 2-3 tablespoons of the crab mixture. On the top left section, layer thinly sliced cucumber and avocado. Spread a ½-inch layer of rice over both the top and bottom right sections.
Fold the sandwich by bringing the bottom left section up, then folding to the right, then down, creating a compact layered sushi sandwich.
Pan-Fry for the Crispy Finish
Heat a generous amount of neutral oil in a pan over medium heat. Place the sushi sandwiches in the pan and fry for 3-4 minutes per side until golden brown and crispy. Flip and fry the other side for another 3-4 minutes.
Serve with Spicy Mayo
Whisk together kewpie mayo, sriracha, and lime juice to create a simple yet flavorful dipping sauce. Serve warm and crispy for the ultimate sushi sandwich experience!
Storage
These sushi sandwiches are best enjoyed fresh for maximum crispiness, but you can store them in an airtight container in the fridge for up to a day. Reheat in a pan to restore the crunch.
Tips
- Don’t over-stuff the sandwich: Too much filling will make it hard to fold and may cause it to break apart while frying.
- Use warm water for rice paper: If the water is too hot, the rice paper will become too soft and difficult to handle. Shake off excess water so the rice paper is dry before you fry it.
