These meatballs are really versatile. We like ours cooked in either BBQ Sauce or Sweet & Sour. I'm sure a tomato sauce would also be fantastic. I usually make a giant batch then divide them up into bags to freeze.
1 1/2 pounds ground beef
1/3 cup oatmeal or breadcrumbs
1 tsp garlic powder
1 tsp salt
1 tsp black pepper
1/2 tsp dried oregano
1 Tbsp dried parsley
1/3 cup milk
Mix all ingredients together in a large bowl.
Shape into small meatballs, about 1 inch. (at this point, you can place them on a baking sheet and freeze, or cover with plastic wrap and refrigerate up to 24 hours before using).
Place the meatballs in the crockpot.
Pour your sauce of choice over top. (We like BBQ or Sweet & Sour)
