What hikermor said ^^ -- I have canned goods, an assortment of Mountain House freeze dried stew and veggies, Tanka bars/bits and other energy bars, and MRE's. Canned goods are by far the most cost effective and they also last beyond their end date. Another thing about canned goods over freeze dried is that you don't have to use water rehydrating them. If backpacking you need to have a source of water, or keep what water you have for drinking and don't use it to rehydrate. You can go much longer without food than you can without water.
