I nuked up a butternut squash (most any hard, winter squash will do), and dehydrated some. The first batch, I spread out about 1/4" thick on waxed paper. DO NOT, I repeat, DO NOT use waxed paper for fruit or vegetable leather. You can use plastic wrap, but I prefer parchment paper. It is silicone treated, works perfectly.
Once the goo (squash, berries, apple sauce, tomato paste, etc.) is partly dry, peel it off the parchment and turn it upside down for thorough, even drying.
Fruit leather can be cut into strips for easy chewing. I cut squash into little squares about 1/4" X 1/4" for easier re-hydrating. Carry in a Ziploc bag, add a bit of hot water & reseal. Add carefully so as to not add too much. Near end of re-hydration process, add some sugar, butter, & salt to taste.
Halve an apple, cut into narrow sections, cut core from center, sprinkle with lemon juice, let dry some, sprinkle with cinnamon, and dehydrate until a tough, leathery consistency. Eat raw, stewed, or dice up into either oatmeal or beans.
