Here's a way to save money and have some fun...make your own sushi at home. If you have kids, let them pick their own foods to place in the rolls and then they can have some fun in the kitchen with you.
Nori sheets filled with:
Cooked brown rice tossed in soy sauce
Red pepper slices
Lots of cilantro
Red pepper slices tossed in soy sauce and cracked black pepper.
These would be good served with slices of wild salmon sashimi or grilled shrimp.
