Onigiri is a small rice sandwich, which in Japan is usually served in the shape of a triangle. The Japanese attach great importance to the striking appearance of this small dish. Onigiri reigns supreme everywhere - whether in Japanese street stalls, restaurants or konbini. The rice sandwich can most often be bought as a ready-made treat, wrapped in foil. It is an integral part of children's breakfast at school. Japanese people also like to take onigiri for lunch to work. The biggest advantage and reason for the popularity of the treat is that it tastes great and is filling for a long time. There is no single recipe for onigiri, as every region in Japan has its own recipe for the sandwich. In konbini, you can buy them with tuna, seafood, salmon, omelette or seaweed, among others. So you can try a completely different dish every day, with a different topping or filling. In order not to waste a grain of rice, the Japanese often make onigiri using, for example, rice after dinner. It's hard to find a place in Japan where they don't sell this iconic triangular delicacy.
