Uses for ground beef:
Why not make a big supply of meat balls. Your favorite mix--bread crumbs,
minced onion (or dried onion flakes), garlic, salt, pepper. Form into
meatballs. (I find the easiest way is to press the ground meat mixture onto a
flat surface, cut into squares, then pick up each square and roll and shape
it into a meatball.)
Place on a baking sheet and freeze, so they don't stick together. Pour them
into a plastic baggie and freeze. Then you can just take out what you need for
your dish--meatballs and onions over rice, meatballs and mushrooms, spaghetti
and meatballs--whatever.
