Cut the apples into 1/4" thick slices, core
Wrap the apple slices with the slices of ham.
Arrange the wrapped apple slices in a single layer, onto clean dehydrator trays. Leave plenty of room for air circulation.
Set the dehydrator's temperature to the fruit/vegetable setting, set a timer for two hours.
After two hours, start checking the apples periodically, until the desired texture is achieved. Dehydrating times will vary but the longer you dehydrate apples the crispier they will become.
Allow to cool before serving.
