Are you looking for meatballs for spaghetti or the ones you use as sort of a starter?
If for a starter, i have a good one:
If you want to make your own meatballs have at it, but i buy the frozen ones.
Put them in a crock pot or slow cooker and add
One bottle of barbeque sauce
one cup of brown sugar
one bottle of pinapple ice cream topping if you can find it
stir and let simmer for a few hours
Sounds weird, but it is soooo good, great for summer get togethers as it's so easy
