Preheat your oven to 375 degrees.Cut up the pizza crusts with the sweater cookie cutter. I got 2 out of each slice. Save the scraps though! You can use it to cut out mini shapes for the sweaters like Christmas trees, a reindeer, even small circles for ornaments.Coat with a thin layer of pizza sauce and top however you want.Place on a baking sheet lined with parchment paper. Bake for 10 minutes or until lightly browned to your liking.
