Food is a very individual thing. Go to the forum section on food and read the older posts. I personally like to cook. A fellow I know did the Sierra High Route (180 miles of off-trail travel) in 12 days on a total vegan non-cook diet! Another fellow I know did 30 days on nothing but macaroni and cheese! Whatever you do, read the food labels to be sure you get sufficient calories per day (usually 2,500-3,000) and take between 1-2 pounds per day (this means most has to be dried or freeze-dried rather than fresh or canned). If you cook, be sure the pakaged meals do not require more than about 10 minutes of cooking or else you will be carrying a lot of gas. And keep it simple. You should be able to get by on one small to medium sized light weight pot, one spoon and a drinking cup.
