My family loves meatballs and this is such an easy way to make them on a busy weeknight. It also means we can serve it in many different ways...for instance my kids prefer spaghetti and meatballs and my husband prefers meatball subs. I like my meatballs and sauce over spaghetti squash. If you're not using a lean meat for this, then you might want to brown the meatballs under the broiler for a few minutes on each side first...this will allow you to drain a lot of the grease before adding the meatballs to the slow cooker.
