This recipe is just a list of ways to eat wiener sausages! Eat as a snack. Use it as a side dish. Use it in bentos.
My husband requested "add garlic powder!" And I have used it ever since. I didn't use garlic powder before that.
Notching the sausages helps to keep the skin from breaking and lets the flavor soak in. The rest is up to you.
Enjoy Japanese food around the world.
