There’s a middle ground between buying kits and the teensiest containers of everything, and roasting your own whole chickens, combing the sales flyers, and making your own salsa. Yes, if you’re trying to eat for pennies the latter is the way to go, but if you’re just aiming for cheaper than eating out, you have a lot of room.
A couple cans of beans, a can or two of stewed tomatoes, and some browned ground beef = a nice hot pot of chili. Some spices would be nice, maybe an onion, whatever you have on hand. You can simmer it in whatever pot you have. Sure crock pots are convenient, but not that much more convenient than cooking the above in a regular pot with a lid (if you brown the meat first, all you’re doing in the pot is bringing everything up to temperature and letting the flavors blend).
Cook regular rice in a regular pot, about 5 minutes before it’s done add frozen veggies, some cut up pieces of cheese, and whatever seasonings are around or sound good. That’s a way cheap one, probably $10 buys enough for 6 or 7 of those meals for two people.
Pasta (a shape like maybe bowties or spiral, not long pasta like spaghetti), some kind of “cooking soup” (cream of chicken, broccoli cheese, something like that), cut up veggies, maybe cooked meat of some kind. That one can be done as a casserole or on the stove.
Get some cold cuts or deli meat, a couple of tomatoes, a jar of pickles, and a block of cheese, and some kind of bread you like. That’s lunch for, what, a week? Of course, there’s nothing wrong with having sandiwches for dinner either.
Heck, spaghetti and a jar of sauce.
Food cheaper than restaurant food doesn’t need to be the result of lots of time. The cheapest food possible does, but at $8 without drink or tip for a basic dinner entree out here in the middle of nowhere, the grocery store can beat that with less time than you’d wait for your food.
I know some foodies are going to be offended that I even said things like “whatever spices you have around”, but honestly people, this isn’t rocket science. You don’t need fresh cooked chicken and beans you simmered yourself for hours to have dinner. Canned beans, frozen veggies, and condensed soup in a can is food too.
