Preheat oven to 450 degrees F. Line 2 baking sheets with parchment paper and spray them with cooking spray.
Drop tablespoonfuls of Parmesan cheese 2 inches apart on the prepared baking sheet. Flatten them out to the size of a potato chip. Sprinkle selected spice on to each pile.
Bake in the preheated oven just until edges start to turn golden brown, 3 to 5 minutes. Cool on the baking sheets for 2 minutes; lift off with a spatula and transfer to a wire rack to cool until firm, about 5 minutes.
These make a great snack, a fun crisp in a salad or as a pasta garnish.
