Cook Short Grain Rice according to package instructions, but only rinse lightly or not at all, since the starch will help bind and hold the shape of your rice mold.
Shape the rice into 5 rectangles with hands or in a sushi mold.
Spread spicy mayo over top of each rice mold.
Cradle the tomato slice over each sushi rectangle and top with an avocado slice.
Tie a strip of nori around the middle of each sushi like a belt and fasten it with a dab of water.
SUGGESTION: Garnish with grated ginger and serve with customary wasabi and teriyaki sauce for dipping.
