Oh crap, you just reminded me. I had a bunch of meat in my dehydrator and I needed to move the trays around. Oh well. It'll still come out good.
Here's what I do now. This is also what some "professional" long distance hiker friends of mine do, too (they eat basically a primal diet). This makes the best food for backpacking.
Get a cheap dehydrator. Look in thrift stores and garage sales.
raw veggies: greens, carrots, zucchini, corn, pretty much anything that is good raw
cooked veggies: starchy things like celery root, rutabaga, sweet potatoes and yams. Cook, mash, smear on parchment, dehydrate (takes a long time for sweet potatoes) then run through the blender to take the sharp edges off
Purchase these because it's cheaper and onions stink up the house
dehydrated onions and tomatoes
Beef tallow melted and mixed with shredded coconut and congealed in muffin tins
Pemmican (beef tallow and dried beef)
Pemmican bars (beef tallow and dried beef with added stuff for flavor like dried cherries)
Dehydrate cooked boneless, skinless breasts chopped up, or canned chicken
Dehydrate ground beef, lean as you can find, cooked and rinsed with water to remove all fat
For your meals, mix some of the veggies, the starchy veggies, and cooked meat in a plastic container (ziploc, old peanut butter jar) and add water. Do this one meal in advance (i.e. for lunch, fix this up at breakfast. For dinner, fix it up at lunch.) Then, at meal time, either eat it cold with olive oil and/or parmesan cheese or heat it up and melt some pemmican or tallow into it. Add salt or other spices, dried onions or tomatoes or whatever you like. I guarantee you will love this.
In addition to this, if you don't mind oats, there's a pretty good bar out there called Journey bars that come in interesting savory flavors. Then there are the usual tuna or other meats in the foil, hunks of cheese, nut butters, salami etc. that most people think of.
