I looked around and all of the porcupine meatball recipes that have been posted include extra and (I think) unnecessary ingredients like Worcestershire sauce. This is the recipe my family has been using since I was a kid. They're very easy to make, taste great with ground beef or turkey, and freeze well. A couple of notes: if you use onion, chop it so it isn't only about double the size of the rice (or less). If it's too much larger it might not be as easy to form the meatballs and could be weird to bite in to. The rice you use should be uncooked Minute Rice, the kind that cooks in like 5 minutes or so.
