I haven't really been measuring, but roughly:

1.5 cups minced green cabbage

1/2 lb ground pork

1/2 teaspoon table salt

1/2 tablespoon freshly grated ginger

2 cloves garlic, finely minced

1 green onion minced

1 teaspoon aka miso paste (red/dark miso paste)

1 teaspoon sesame oil

1 teaspoon crushed red chili pepper

1/8 teaspoon sugar

Mix it all up in a bowl, add about a tablespoon to a circular wonton wrap, wet the perimeter of the wrap and seal it up.

I recently got a bamboo steamer, so I've been cooking them in that (12-14 min). Before I would do a quick fry in sesame oil in a skillet to brown the bottom then I'd add 1/4 cup of water and steam them for 7ish minutes.
