Jiaozi for a Crowd

I'm pretty lucky when it comes to guessing how much jiaozi to make for a crowd, but I thought it might be okay to document it, cause last night we got it just right.  


Jiaozi for a Crowd (19)


1/2 head nappa cabbage
1 bag spinach
2 bunches of onion
3 chunks of ginger
2 pounds ground pork
3 packs wonton wrappers


Cook 5 cups of rice.
