Preheat the oven to 200 degrees F.
Mix the sugar and cinnamon in a bowl; reserve.
Place each type of sliced fruit on a separate silicone-lined baking sheet. Sprinkle with some of the cinnamon-sugar.
Bake the apples until the edges curl, about 2 hours. Transfer to a cooling rack. The chips will crisp as they cool.
Bake the mango and pineapple slices for 30 minutes, then flip and sprinkle with more cinnamon-sugar. Continue to bake, flipping the mango and pineapple slices every half hour, for 2 1/2 more hours. Transfer to a cooling rack. The chips will crisp as they cool.
Serve the fruit chips with the cheese cups.
