For the Sushi Rice Bun:

  • ½ leftover cup sushi rice prepared with 1 tsp seasoned rice wine vinegar
  • Two small similar sized bowls
  • Nonstick spray

For the Spicy Tuna:

  • * ¼ lb raw ahi tuna
  • * 1 tsp kewpie mayo
  • * ¼ tsp sriracha
  • * ¼ tsp sesame oil
  • * A few dashes of soy sauce


  • * ¼ avocado sliced
  • * ¼ tsp kewpie mayo
  • * ¼ tsp sriracha
  • * ¼ tsp eel sauce
  • * ½ tbsp cilantro chopped
  • * ½ tbsp crispy fried garlic


Assembling the Sushi Rice Bun

  • Prepare sushi rice according to the directions on the bag and then add about 1 tsp of seasoned rice wine vinegar per cup of rice - this is what will give it the sticky texture and will help the rice patties stay together.
  • Find two small bowls and spray them with nonstick spray.
  • Take two small handfuls (about ¼ lb each) of the sushi rice and pack them into the bowl, wrap in cling wrap and put in the fridge for at least two hours and up to 48 hours. Remove from fridge and gently slide out when ready to use.

Assembling the Spicy Tuna

  • Roughly chop ahi tuna into small chunks and place in a bowl. Add kewpie mayo, sriracha, sesame oil, and soy sauce and stir. Set aside.

Assembling the Sushi Burger

  • Gently remove one-half of the sushi bun out of the bowl and lay avocado on top.
  • Add the spicy tuna mixture and add a drizzle of sriracha, kewpie mayo, and eel sauce.
  • Top with cilantro and the other half of the sushi bun and sprinkle with the crispy fried garlic.
