Onigiri is an awesome dish that can be eaten right about any time of the day. It can be breakfast, a snack, or a meal on the go. You can stuff it with your favourite ingredients and it can be prepared at home or bought in specialized restos or convenience stores.
Much like sandwiches in the West, onigiri are readily available in convenience stores or speciality shops in Japan. Onigiri are eaten with hands (no chopsticks or spoon) and commonly seen in bento boxes. They are a great for a quick and easy snack. They look cool to eat and are pleasing and really tasty, a fun and filling alternative to sandwiches for lunch.
