When I back pack one thing we carry is ramen noodles. I use that as a starter and add summer sausage, cheese, freeze dried veggies, some curry. Rice works also. Some of the freeze dried meals availible are good. Spaghetti is good to bring. If you want to bring meat, get a small cooler and put some dry ice in and the meat will stay frozen. That will keep ice cream frozen also. Not a bad treat miles from nowhere. Plus you'll be the envy of any one that might run into. Another thing thats good is to order a pizza hut pan pizza, Wrap each piece up and when it's time to eat just warm it in a pan over low heat or over some coals on alum. foil. It will taste like you just ordered it. Noodles with butter and parm. cheese and sun-dried tomatos........Is it dinner time yet?
One other thing, bring a trash bag.
