This recipe is perfect when you're strapped for time, and kids will think you're super fancy for serving something sushi-like for dinner (and have a blast building their own handrolls). Just grab your favorite vegetables (cucumbers and asparagus work well), some steamed shrimp, and soy sauce to fix it all up.
In a bowl, combine the hot rice, rice vinegar, white sugar, and salt. Mix thoroughly. Taste and adjust the seasoning. Let cool slightly.
To assemble, cut the nori into squares for a handroll (or "taco"). Layer on the rice, cucumbers, shrimp, and avocado. Roll and serve with soy sauce and wasabi, if desired.
