Preheat your oven to 400℉. Line a 12x17" metal sheet pan with parchment paper. Sprinkle on both cheeses to the pan to form an even layer, covering the bottom of the pan.
Remove the core/seeds from your apples and cut them into medium thin slices (1/4 -1/2 inch thick). Place them on the cheese so that they are touching (they will shrink when baked).
In a small bowl, mix the cinnamon and sugar and sprinkle this on top of the apple slices. Bake for 18-20 minutes or until the edges turn brown and the middle turn golden brown. Allow to cool for a few minutes and then tear apart and enjoy!
