Only three posts in and this thread is making me hungry already!
MRE components and MH-style freeze dried meals are wonderful, and there's always lots at the grocery store and the good old bulk food store. Tthere are so many packable options that I find it fun to make my own. One of the hardest tasks in trip planning, for me, is deciding on a menu. Camp and trailside cooking is one of my favourite things, especially when I have the chance to cook over a wood fire.
Someday I'll try home dehydrating, but for now, our local outdoors store has started carrying simple "unreciped" dehydrated ingredients - beef, chicken, pork, onions, peas, corn, carrots, fruit, etc... without sauces, seasoning, etc. so I get benefit of longer storage and I get to create my own meals from scratch. More labour intensive that pre-made meals, but a great compromise that lets me get my creative camp chef on without having to carry the weight of fresh fully hydrated ingredients.
