Great to serve for breakfast. It's super-easy.
When I was in high school, I used to make breakfast and bentos for myself. That was when I thought of this recipe. I used to eat this all the time since it's easy and filling.
You can also use ham or canned tuna instead of fish sausages. If you have daikon sprouts or green onions, sprinkle on top for color.
Enjoy Japanese food around the world.
