Also, learn the price difference between fresh vs prepared. Pasta is a good example- it's not cheaper to make it at home, if I remember correctly. It's better if made at home, but if you don't mind boxed pasta then you should eat boxed pasta. Also, if you've got a local butcher, consider getting your meat there.
