Now on to the meat balls. Preheat the over to 475. Blend milk and bread with rest of onion mixture. Add sausage, parsley, garlic, cheese and eggs. Mix beef with this mixture but not to much as you don't want tough meatballs. Roll into 2 1/2 inch balls, you should have about 16 balls. Bake until well browned, about 30 minutes or so. Put the meatballs into the sauce and simmer for about 15 mins.
