Brown the veggie ground round in a skillet. Combine the remaining ingredients (up to the wonton wrappers) in a bowl for the filling. Add the ground round to the bowl.
Fill the wonton wrappers with 1 tsp. of the filling. Using your fingers, wet the wonton wrapper along the edges. Fold wonton in half and press to close on the edges.
Once I was done that step I set the dumplings on a waxed paper covered cookie sheet and then froze the dumplings. The next day I peeled them off the waxed paper and gently put them in a freezer bag so we can just pull out however many we want to cook up at a time.
When you are ready to cook the dumplings, place a piece of waxed paper on a steamer plate in your wok and steam with the wok cover on for 10-15 min until done.
Serve with sauce.
Combine all the sauce ingredients in a small bowl. Mix to dissolve the sugar. Serve.
