A dehydrator has been on my "low priority" things to buy list for years! I used to eat a lot of raw food, and a friend of mine who has been 100 percent raw for years, invited me and some others round to his home for dinner. The menu included dehydrated cauliflower florets, which sounds awful, but with a dipping sauce made from something like tahini and paprika, they were delicious! So... you could try experimenting with raw veggies.
Raw veggies sound good, I've started experimenting with carrots, but I need to do the cutting better... They really shrink alot after losing their water!
