We learned a really easy way to cook beans. Dried beans are very inexpensive and very nutritious. They are a good buy for your money when you are trying to spend as little as possible.
Put your beans in an oven proof pot - or get an oven proof casserole out to pour the beans into - and cover with water. Bring to a boil.
Set the oven for 325 degrees.
When beans boil, put pot into oven, or pour into oven proof casserole and then carefully place in oven.
Check your beans about 30 minutes apart. Most will take about 2 1/2 to 3 hours.
You can cook several pots/bowls of beans at once this way.
When the beans are done to your liking, remove from oven and allow to cool completely. Scoop one or two cup servings and freeze in heavy freezer bags.
The beans are one of the best freezable foods there is. To thaw, place in microwave (we don't own one, so can't tell you for how long), thaw on counter or in refrigerator - even in a bowl of cool water if you're in a hurry (and don't have a micro-thingy)
