Free meat for omelets or pizza

Save all the little bits of leftover sausage, bacon, or ham - even the tiniest - and keep it in the freezer. It doesn't matter if it's not all the same type (or even flavor) when you use it on a pizza or in an omelet. You can mix it into cornbread, too, and serve with beans or dried pea soup, but that's not as frugal as using it in the main course.

Popcorn to cornmeal

Got popcorn that won't pop? Mill it into cornmeal and make yourself some delicious corn bread! If you don't have a flour mill, put the corn in a cloth bag or wrap it loosely in cloth, then crack it by hitting it with the flat side of a hammer or something similar. Finish milling it in your blender or food processor. Sift out the larger pieces process again.

Cooking fat

If you eat bacon, you might as well save the bacon grease to use in other things. Try it instead of butter on popcorn, or put it in green beans or use it to grease the pan for cornbread. It's free and you eat it anyway when you eat the bacon.
