Once your rice is seasoned, find two small bowls and lightly coat them with nonstick spray. Pack your rice into the bowls, wrap them in cling wrap, and refrigerate for at least 2 hours. This chilling step is key for shaping the buns later.

While your rice is chilling, it’s time to whip up the spicy tuna mixture. Dice the ahi tuna into small chunks and place them in a mixing bowl. Add in the Kewpie mayo, Sriracha, sweet chili sauce, sesame oil, and soy sauce. Stir everything together gently, and your spicy tuna is ready to rock!
Assemble the Sushi Rice Bun
Once you’re ready to create your spicy tuna and avocado sushi burger, gently remove one half of the sushi bun from the bowl. Place a few slices of avocado on top—it adds a creamy, rich flavor that perfectly complements the tuna.
Build Your Sushi Burger Masterpiece
Now comes the exciting part! Spoon the spicy tuna mixture on top of the avocado. For added flavor, drizzle extra Sriracha and Kewpie mayo, followed by eel sauce. To finish, sprinkle with cilantro and add the other half of the sushi rice bun, topped with crispy fried garlic for that much-needed crunch.
And there you have it! Your spicy tuna and avocado sushi burger is ready to enjoy—perfect for a light lunch or an exciting dinner option that impresses and delights. Happy cooking!
