Beans! Chili! Hamburger!
YES, HAMBURGER! Load up the crockpot with hamburger, finely minced onion and celery (carrots, too, if you want!) and garlic. Cook all day, chopping it up occasionally while it cooks with a pancake turner.
After it has cooked, keep chopping with the pancake turner, until all chunks are gone. If you bought the expensive stuff, add some water and stir it all up.
Stick it in the refrigerator overnight.
The next day, remove the congealed grease and throw away. Then divide the cooked burger into meal-sized portions and place in quart freezer zipper bags. Flatten the bags and freeze.
One bag for tacos, one bag for spaghetti, one bag for sloppy joes…you get the idea. No need to brown and drain, just throw the frozen block in the pan and cook like crazy!
