I have made this several times. If you bake the meatballs before you put it in the Crock pot, you will have less grease. I also add Garlic salt, Knorr's beef seasoning, Italian seasoning, and Pepper to the Meat mixture. To the Store bought sauce I add, Salt, Garlic, Garlic salt, Italian seasoning, Sugar, for a richer flavor. My Family, and Friends LOVE this.
