i was talking to my bro about backpacking food. we used to just buy backpacking food in the plastic bags at rei and the like, but they have a decent amount of air, are kind of overly spiced/salted, and are bulky. we started thinking we could bring a zip lock bag of brown rice, some chicken in plastic pouches you can buy in grocery stores (or fish) and some vegetables and just add in small sauce packets or whatever. it would be cheaper and smaller. that being said, how long would you suppose the chicken or fish in packets would last? as far as vegetables, frozen ones that you let thaw then pack (its cheaper) probably wouldn't last near as long as raw vegetables would they? because they have inherent moisture in them i mean. i would guess raw broccoli and carrots would be the best since they have very little moisture held within.
just trying to hash out ideas for cheap, light weight food that won't go back if on the trail for 3-4 days.
