Cook and season the rice: Rinse until water runs clear, cook according to package instructions, and mix gently with rice vinegar, sugar, and salt. Let cool slightly.
Prepare the crab: Shred real crab or chop imitation crab into bite-sized pieces.
Assemble your bowl: Start with a base of sushi rice, then layer crab, avocado, cucumber, and nori strips.
Add toppings: Sprinkle sesame seeds and drizzle with soy sauce, spicy mayo, or sriracha. Add pickled ginger if desired.
Serve immediately and enjoy sushi at home without the fuss.
