Dried fruit is great as a snack on their own or chop it up for use in oatmeal and baked goods.
4 small apples, cored, peeled, and cut into 1/8-inch slices
Set Sun Oven out to preheat. Line 3 baking racks with parchment paper or silicone mats.
Arrange the apple slices in a single layer on the prepared baking racks. Sprinkle sugar (if using) and cinnamon evenly over the apple slices. Stack the racks in the Sun Oven. Close the glass door but leave it unlatched to allow the steam to escape. Remove the apples when they are dehydrated. Store in an airtight container.
