04 - Roll dough out on a lightly floured surface to a 10x14-inch rectangle.
05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly over the dough.
06 - Starting from a long side, roll dough tightly into a log. Slice into 12 equal portions.
07 - Arrange rolls seam-side down on prepared baking sheet. Brush with melted butter and sprinkle with grated Parmesan.
08 - Bake for 18 to 20 minutes until breadsticks are golden and cooked through.
