Combine all ingredients for the sushi rice in a bowl, and stir together. Set aside.
2 cups cooked short grain rice, 2 tbsp rice vinegar, 1 tsp sugar, 1/2 tsp sea salt
Add all ingredients for spicy tuna to a bowl, then mix. You can add more mayo to make it more creamy if you want.
10 oz canned tuna, 3-4 tbsp Kewpie mayo, 1 tbsp sriracha
Prepare a shallow, wide bowl of cold water. Dip 1 rice paper in water, then place on a moist cutting board. Add a toasted nori sheet towards the bottom half of the rice paper.
Add 1/4 cup rice over the nori, then add 2 tbsp carrots and 2 tbsp of tuna.
Top with a layer of cucumber slices, a layer of sliced avocado, then another toasted nori.
To roll, bring the bottom portion of the rice paper up to cover some of the filling, then fold the sides in. Roll up and away from you to wrap with the remaining paper on top.
Add a thin layer of toasted sesame seeds to a plate, then roll the sushi roll on the plate to cover on all sides. Transfer to a parchment paper lined plate or baking sheet to keep from sticking while you repeat with the rest of the rice paper and filling.
Toasted sesame seeds
Heat a nonstick skillet over medium low heat, and add a thin layer of avocado oil. Once heated, add the sushi rolls in a single layer without touching other. Cook for 3 minutes on each side until golden and crispy. You may need to do this 2 batches.
Avocado oil
Remove from heat and serve with soy sauce for dipping. You can add wasabi to the soy sauce, if you wish!
2 tbsp soy sauce, 1/2 tsp wasabi
