Preheat oven to 375. Line a baking sheet with parchment paper, and lightly mist it with non-fat cooking spray.
Lightly dust a flat surface with flour, and roll out pizza dough into a rectangle, about ¼” thick.
Cut out 16 triangles, about 3” wide and 6” long.
Place 3 slices of pepperoni on the bottom, wide end of each triangle. Place a cheese stick half on top of the pepperoni. Roll up, and place 2 in. apart on a baking sheet, seam side down.
Bake for 10-12 minutes or until golden brown. Let cool for 5 minutes.
Meanwhile, in a small bowl, melt butter and stir in garlic powder and Italian seasoning.
Brush each pepperoni cheese stick roll-up with the melted butter. Serve with marinara sauce or ranch dressing to dip.
