If you have these made ahead and ready in the freezer, all it takes is the time to pop them in the crockpot.
HAM BALLS: Combine 3# ground ham 2# ground pork, 2 cups quick oatmeal, 2 cups milk, 1 egg. I use my Kitchen Aid mixer to mix. Make small ham balls and put in greased baking pans with sides. Ham balls can be touching. Mix up sauce: heat to dissolve sugar but don't boil. 1 cup white or cider vinegar, 3 cups brown sugar (or less), 1 cup water, 2 Tblsp. prepared mustard. Pour over ham balls. Bake 90 minutes at 350. When cool, store in freezer containers. Our meat market has ground ham and pork in the meat case.
