I love dried fruit to eat as a healthy snack. You can make delicious apple crisps from fresh apples very easily. Just wash and dry the apples, then cut the apples with skin on, into very thin slices. You can either leave them in the sun on a drying rack during the day for 2-3 days (just bring them inside at nighttime) or dry them in your oven.
If you use the oven cover the wire rack with baking parchment paper and arrange the apple slices. Heat the oven to 140 F and place the apples inside. Leave the oven door slightly open and let the apple slices dry out for about 4-5 minutes.
