Preheat the oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
Unroll the pizza dough on a lightly floured surface and divide it into 8 equal pieces.
Roll each piece into a rope about 8 inches long, then twist the ends slightly to form a bone shape.
Place the shaped dough on the prepared baking sheet and brush each piece evenly with the melted butter.
Sprinkle the garlic powder, oregano, and Parmesan cheese over the top of each breadstick.
Bake for 12 to 15 minutes until the breadsticks turn golden brown.
Warm the marinara sauce in a small saucepan over low heat while the breadsticks bake, then transfer it to a serving bowl.
