We bought cattle. My BiL gets the first calf and that pays for the feed. His best friend has A hog operation and a bunch of German immigrants in their community (Mennonites) raise chickens for eggs and meat. Our only problem right now is freezer space.
Growing up, we always had a couple steers and a hundred or so chickens. We always had a big garden too, and mom would can and preserve a lot of food for winter. When we started leasing and selling land, that stopped and we became more dependent on the grocery store.
I've reversed that the last couple years. My (small) pantry is full of stuff I grew, and bought at the market, and preserved. I've got about 20l of tomato sauce, and it's the best ever! Super sweet and tomato-ie. And all that is in it is, tomatoes (campbell and beefsteak), a little citric acid, and some salt. And about 15l of stewed roma tomatoes, same ingredients. And my eggplants did very well, so I have 2l of dried and 4l of grilled eggplant in oil. Cauliflower, sauerkraut, sauerbraten, spinach, sweet corn, fermented cucumbers, kosher dills, green tomato pickles and chutneys, chow-chow, crab apple sauce from the trees, and the best strawberry jam and jelly ever - sweetened only with that applesauce!
Plus things from the farmers market; concord grape jelly, canned peaches, fruit salad, a really good quince marmalade and quince fruit salad with oranges and grapefruit.
If I ate more meat, I'd make more salumi and rillette. Things that don't need a freezer.
That's how you do it, without breaking the bank.
