I would buy hamburger, maybe a roast or two, some sausage. You can use the hamburger to make spaghetti, hamburgers. With a roast, you can have roast, potatoes and a veggie, with the leftovers you can make sandwiches.
Sausage used for sandwiches or for your spaghetti. I try to pick meats that I can get a few meals out of. A ham, for a ham dinner, ham for omelettes one night for dinner, hot ham sandwiches.
And if you like pea soup, use the ham bone for that…. Hope this helps.
