Heat oven to 375 F.

To make sushi rice: Mix cooked rice with rice vinegar, sugar and salt. Let cool slightly.

To make tuna mixture: In bowl, combine tuna (no draining needed), mayonnaise, Sriracha, soy sauce and wasabi, if desired. Mix well.

To assemble: Cut nori sheets into squares and press into cups of muffin tin to line them.

Fill each nori-lined cup with sushi rice, pressing gently to form small nest shape.

Sprinkle furikake over rice then top with spoonful of tuna mixture.

Bake 8-10 minutes until heated through and edges are slightly crispy.

Remove cups from muffin tin, drizzle with spicy mayo or Sriracha and top with wonton crisps.
