Make sure everything is in very small pieces, especially the meat, so it will rehydrate in a reasonable time. I've done stew and it worked fine.
But no peas. I tried dehydrating a chicken casserole with peas once. After 15 minutes' boiling, the peas were still like buckshot--hard enough to break a tooth. I had to eat around them and pack out the peas. If you want a dish with peas, dry the dish without, get some freeze-dried peas from "Just Tomatoes" and add them after the rest of the dish is dehydrated.
The real lesson I learned from that incident is to try everything out at home, first!
If you're not familiar with Sarah's "Freezer Bag Cooking" site, she has lots of info on dehydrating there. I'm an avid fan!
