Simple snack that only uses on ingredient!
Cookie Sheet
3 small apples per cookie sheet
Parchment Paper
Preheat oven to 250 degrees, 235 if you have a convection oven.
Use apple slicer to core and slice apples. I have this one. If you don't have this tool, just core and thinly slice apples.
Line cookie sheet with parchment paper. Arrange apple slices very closely on pan, being careful not to overlap. Bake for 2 hours. Let cool and store in an air tight container.
