I dehydrated a lot of meals for backpacking this year.
Winners:
1) Strawberry mash -- dried to fruit leather. Yum
2) Dried apples, berries (if you slice them they will dry)
3) Mashed sweet potatoe -- rehydrates nicely
4) Chicken. Yep, take a crockpot cooked chicken, shred and then dehydrate it. Will make leftover chicken last forever, is great to eat dry or rehydrate. I will make this for kids to add to their lunches this year as it does not go bad for days. Keep in freezer if not used in 2 weeks. So good I made it twice.
5) Pasta sauce -- I did a red pepper / cream / goat cheese / garlic sauce and dehydrated it. Came back rehydrated so nicely!
6) Dehydrated veggies (peas, corn, carrots, cooked frenched greenbeans, cooked onions)
So, if you ever have leftovers (cooked) and don't want to freeze them, but eat them much later, try dehydrating. must spread in 1/4" layers, or less.. but that is the main rule.
