Salmon Onigiri is a flavorful variation of Onigiri that features grilled or cooked salmon as the filling. To make Salmon Onigiri, start by cooking the sushi rice and letting it cool slightly. Meanwhile, prepare the salmon by grilling or cooking it until it is fully cooked and flaky. Once the rice is ready, take a small handful and shape it into a triangle or oval shape. Make an indentation in the center and place a piece of salmon inside. Close the rice ball and wrap it with a strip of nori seaweed. Salmon Onigiri is a delicious and nutritious snack that is packed with omega-3 fatty acids from the salmon. It can be enjoyed as a light meal or as part of a bento box lunch.
