Mix those ingredients well and pour over one bag of meatballs.
Cook in crock pot on low for 2-3 hours so the sauce absorbs.
Tip: If I'm in a hurry, I have put the meatballs on a baking sheet and stuck in the oven for about 15 minutes at 400 degrees to thaw them first. But, generally, cook them from their frozen state. If you use Gordon's, you shouldn't have a problem with them being greasy. I have used other brands and found that it sometimes was a problem and had to drain grease off them.
