freeze dried foods are the shit. so delicious when youre climbing, backpacking, or just plain hungry. I'll pay $4-$5+ at REI (good ol dividend) for a solid freeze dried meal. Calories to price and weight isn't exactly fantastic, but its still delicious.
MREs are... interesting. Somewhat ok of a price for a "meal" but they only pack like 1200 calories, not 2000 plus. So really, freeze dried>MRE
