  • 1 can tuna in water (5 ounces) drained

  • 1 egg lightly whisked
  • 1 ripe avocado sliced
  • 2 nori sheets

  • In a bowl, combine the drained tuna with light mayonnaise, a pinch of salt, and black pepper. Lightly oil a nonstick pan and pour in a whisked egg to make a thin omelette; once cooked, slice the omelette into strips. Slice the ripe avocado into thin pieces.

  • Once your rice cools, place a nori sheet on a chopping board angled towards you. Add a layer of sushi rice in a square with a straight side facing you. Top with filling ingredients: sliced avocado, the cooked egg, tuna mayo, more avocado, and rice.

  • Trim a second nori sheet into a medium square, slightly larger than your fillings, and place it on top of them. Brush the edges of the larger nori with rice wine vinegar, then fold the edges over the second nori to enclose everything tightly. Wrap and refrigerate until firm. If you like, drizzle with sriracha mayo before serving.
