I have to make fruits and veggies into hard chips since my son will not eat anything, unless it crunches. I discovered that you can dehydrate using your oven. I'm sure most people are aware of that, but some may not. My favorite is bananas and apple chips. I just chop them into little rounds and lay them on a slated pan. I heat the oven to about 225 degrees, sprinkle with a little cinnamon, and bake for 2-4 hours..or until they are completely hard. I am beginning to stock up and put back airtight packs of these, a lot of calories for your buck!
Here's a link for some more info. Enjoy!
