Story Behind this Recipe
I wanted to add something green to a bento, so I made this up with things I had on hand. I was considering various flavor options, but ponzu sauce was perfect. My kids ate it up too. Tuna is really great!
Use tuna packed in water or broth for an even healthier version. Adjust the amount of ponzu sauce to taste.
