This is a combination of lots of different recipes. The sauce is slightly spicy, but can be altered by adding more or less crushed red pepper flakes and peppers. We eat these on a sandwich, over pasta, or even on pizza. They freeze really well either in the sauce or alone. If freezing without the sauce, place them on a cookie sheet and place in freezer until solid. Then the meatballs can be placed in freezer bags and added to pasta a few at a time.
