I use mine a lot.
I dehydrate strawberries, apples, pears, blueberries, and cherries and use them in hot cereal, pancakes, muffins, salads, pilafs, and to nibble. I also like to dry some of the strawberries very dry, then whirl them in the food processor to make a powder to make strawberry butter with a touch of powdered sugar.
Vegetables, too, especially tomatoes, some of which I do the powder trick for adding to sauces, soups, etc. Dried tomatoes, peppers, carrots, even corn, can be added to soups. I also dry sliced beets to make "beet chips" for nibbles.
I've also put tomatoes in the food processor, then added basil and oregano to make a "tomato leather" like fruit leather. It is a concentrated bite of flavor to nibble or cut up and toss on pasta or in soup. Italian tomatoes are better because they have more pulp and less juice.
If you have extra or leftover fruits or vegetables, you can dry them and store in a jar for later use. This is especially handy when things are in season, and the storage space is very small compared to canning or freezing.
