<human>:  How to make a spicy tuna roll?
<bot>: To make a spicy tuna roll, you'll need the following ingredients: 1 can of tuna, 1/4 cup mayonnaise, 1 teaspoon of sriracha or chili paste, 1/4 cup chopped scallions, 1/4 teaspoon of garlic powder, 1/4 cup of sesame seeds, and 8 sheets of sushi nori. Start by draining the tuna and mashing it together with the mayonnaise, sriracha or chili paste, scallions, and garlic powder in a medium bowl. Mix together until all of the ingredients are evenly incorporated. Take one of the nori sheets and place on a flat surface. Spread 1/8 of the tuna mixture in an even layer over the nori. Sprinkle 1/2 tablespoon of sesame seeds over the layer. Carefully roll it up and press firmly to keep the roll tight. Cut the roll into 6 to 8 pieces and serve. Enjoy!
