Using a mandoline, thinly slice the apple and pears into “chips” ( I love my hand mandoline, but you can also cut them with a knife into thin slices if you don’t have one).
Place the slices on a Silpat or parchment lined baking sheet making sure not to over lap the pieces.
Bake for 1 hour, turning the “chips” halfway through (if you live in a humid climate, they may take a bit longer).
Cool and serve.
*You can place several cookie sheets in the oven at the same time if you want to make a large amount.
