1 lb of extra lean ground beef (you can use any ground beef or chicken you like, but that's what I use)
several dashes of Worchester sauce
1/4 cup chopped onion (I used red onion today, but any kind of onion will do)
1/2 cup oats (or breadcrumbs)
a few dashes each of salt and pepper
Mix all of this together well.
Form 1 inch round meatballs and put on baking sheet.
Bake in 350* oven for about 20 minutes
You could serve these just as is and they'd be fine. Add some Italian seasoning to them for spagetti meatballs.
Sweet and Sour Meatballs
Make meatballs as directed above. While the meatballs are baking, mix 1 cup of crushed pineapple, 1-2 tbsp finely chopped onion and 1 jar of sweet and sour sauce together. Put everything, including the meatballs in a crockpot/slow cooker on low heat for 6-8 hours. Serve over rice (brown preferrably).
