Step 1

Cut off the bottom quarter of each nori sheet; reserve for another use.

Step 2

Combine chopped tuna, mayonnaise, green onions, and hot sauce in a bowl.

Step 3

Center 1 sheet of nori on a bamboo sushi mat. Wet your hands. Spread a thin layer of rice on the nori using your hands; press into a thin layer, leaving a 1/2-inch space at the bottom edge. Sprinkle with sesame seeds. Arrange 1/4 of the tuna mixture in a line across the rice, about 1/3 of the way down from the top of the sheet.

Step 4

Wet the uncovered edge of the nori. Lift the top end of the mat and firmly roll it over the ingredients. Roll it forward to make a complete roll. Repeat with remaining ingredients.

Step 5

Slice the rolls into 3/4-inch pieces using a wet knife. Serve immediately or refrigerate until serving.
