Believe it or not, it's a LOT cheaper. Not only that, but it's also higher quality food that we're eating. There are three reasons it's cheaper. The first is that we're no longer buying value-added foods. No preprocessed-ready-to-eat foods. This alone makes our food higher quality. We are making it ourselves and control what goes into our food. It's also making it cheaper. A loaf of bread is just costing us maybe fifty cents. Homemade tortillas - even less. I can make homemade corn tortillas for free by using wood ash to slake the Indian corn that we grew this year. Grind it up. Add a bit of water and cook.
This brings us to the second reason - buying bulk. This is undoubtedly the cheapest way to go. We bought a freezer full of beef - all cuts - for $5.30/lb. That's pasture fed, humanely raised beef for less than we can buy a steak from a CAFO steer.
Third reason - no more eating out - enough said.
