A great way to cut your budget in the kitchen is to cook your own beans, instead of buying them in a can.
Jessica, at Good Cheap Eats, describes how she makes homemade pintos and refried beans. She cooks them herself and it proves to be much cheaper than fifty cents a can.
The bag pictured cost $6.39 at Costco. At $0.64/# she can make the equivalent of 4 cans of beans for a lot less money.
You can follow her instructions to make your own beans in a crockpot or on the stove.
