Make them. (i know, it's not the answer you're looking for, but read on...)
I bought a food dehydrator a couple years ago because i wanted to make my own back woods food. It's been AWESOME and i don't even eat dehydrated food that much.
You can dehydrate your own pasta sauce to take with you on backpacking trips, homemade fruit roll ups, corn, etc.
The fruit is obviously endless. Strawberries do well. Really ripe bananas do great. Apples do great.
your cell phone. Yeah, thats right. The last thing that spent 16 hours in my dehydrator was my cell phone. I dropped it in a puddle, so i immediately took out the battery and dehydrated the damn thing - works great.
You can also experiment with jerky.
I guess the whole point is - i didn't even really eat dehydrated food except for camping food. But, after i bought one it's turned out some
wonderful stuff so i'd suggest just getting one.
