My mom breaks the beef into smaller chunks and I freeze them separately.
Yes, that's what we do. Use what we need at present and then freeze the rest. Though if I do chose to make Tacos, I'll simply freeze the meet that wasn't used. Comes out just as good later.
We freeze hamburger patties, brats, Italian sauges, hot dogs, bacon, bread, whatever. When it thaws out it's good as new. Unless of course you've let it stay in there for far too long.
I usually eat less Fast Food in the summer because no fast food will ever be as good ass grilled food and grilled food is the easiest thing to make.
