Salmon Onigiri is a flavorful variation of Onigiri that features grilled or cooked salmon as the filling. To make Salmon Onigiri, start by grilling or cooking a piece of salmon until it is fully cooked and flaky. Let the salmon cool slightly before flaking it into small pieces. Prepare the sushi rice and shape it into small triangular or round balls. Place a spoonful of the flaked salmon in the center of each rice ball and shape it into a triangle or round shape. Finally, wrap the Onigiri with a strip of nori seaweed. Salmon Onigiri is a delicious and nutritious snack that is packed with omega-3 fatty acids and protein.
