Tonight we ate tilapia and rice ball (onigiri).
The way it has been described to me, onigiri is the equivalent of the American sandwich. They have many options at convenient stores, including barbeque beef, tuna, chicken, seaweed, plum and even omlette.
Some rice ball have the ingredient in the inside and can be wrapped with seaweed (nori) and some have seaweed in the rice with one or two other flavors.
