My mother used to make these for me.
I tried sandwiching different things with hanpen, but this recipe is my favorite.
It's so easy and tasty. I really want all of you to give it a try Also this pleases guys and small children.

If you're not serving them immediately, cover the pan and steam. This preserves the melting cheese for a while.
It's also good when cooled, so you can pack them into bentos. For 2 servings. Recipe by *Chyi*
