How can I use the rest of this beef mixture?

I had an urge to make something brand new for lunch today. Got everything mixed up and ready to go, and started boiling my jiaozi (Chinese dumplings).

Never have I experienced such a fail of epic proportions.

My test batch tasted like a bunch of pencil erasers dipped in ginger and soy sauce. I’ve never been good at pie crust, so I blame it on the same principal.

So, now I have about 2 cups of a beef, onion, and cabbage mixture. I don’t want it to go to waste… what can I do?
