I love dried bananas!
Just slice up bananas and dry them, no sugar added. (those very-ripe bananas on sale in the grocery stores work great for this).
The only problem is that I eat them really fast, and the calories add up.
You can also blend very-ripe bananas with other fruits to make fruit roll-ups (you have to get a solid mat to pour the ingredients on, NOT a screen. Usually, these mats are Teflon coated).
I've also made coconut macaroons (raw coconut, almond meal--I got this my grinding up raw soaked almonds to make almond milk: it's what''s left over after the straining--some agave nectar and vanilla to taste. Form into cookie shapes and dry).
I also like to soak raw nuts (6-8 hours for almonds and other hard large nuts, 4-6 hours for walnuts) or seeds (2-4 hours for sunflower seeds), then rinse and dry in the dehydrator. You can add sweetener and cinnamon, or a bit of soy sauce and spices before drying to make flavored nuts). Soaking the nuts starts the germination process, which increases nutritional value--as in sprouts--and removes some of the antinutrients in the husk of nuts that make them less digestible).
You can also dry a lot of garden produce when you have extra in the summer. Dried and reconstituted tomatoes make a nice thick base for sauces and such.
You can find a LOT of ideas for using a dehydrator in some raw-food recipe books (Alissa Cohen uses it a lot for her recipes:

HTH!
