Japanese Tuna Grilled Rice Balls ("ツナ"焼きおにぎり - Tuna Yaki Onigiri)

Directions

1. Filling: Mix tuna and mayonnaise.
2. Scoop 1/4 cup of rice onto plastic wrap and flatten rice. In the middle, place filling on top of the rice. Pull plastic wrap together to shape into a ball.
3. Under lower to medium low heat, grill each onigiri in a pan with butter until all sides form a crispy crust.
4. Brush all sides with soy sauce and re-fry all sides (30 secs per side) until crispy. Be careful as it burns quickly!
