Tuna Mayo Onigiri is a popular variation of the classic Japanese rice ball. It combines the flavors of canned tuna and mayonnaise to create a creamy and savory filling. To make Tuna Mayo Onigiri, start by cooking the sushi rice and letting it cool slightly. In a separate bowl, mix canned tuna with mayonnaise and any additional seasonings you prefer, such as soy sauce or sesame oil. Take a small portion of the rice and flatten it in your hand. Place a spoonful of the tuna mayo mixture in the center and shape the rice into a triangle or ball. Repeat this process until all the rice and filling are used. Finally, wrap each Onigiri with a strip of nori seaweed. Tuna Mayo Onigiri is a versatile dish that can be enjoyed as a snack, a light lunch, or a side dish. It is also a great option for picnics or bento boxes. The combination of the creamy tuna mayo filling and the sticky rice is sure to satisfy your taste buds.
