Preheat the oven to 375 degrees, and line a baking sheet with parchment paper.
Roll out the crescent rolls into eight triangles.
Place a row of pepperoni slices at the widest end of each triangle.
Add a mozzarella stick piece on top of the pepperoni slices.
Roll the dough down over the filling, pinching the edges closed to fully cover the filling.
Place onto the parchment lined baking sheet seam side down.
Brush the top of the rolls with butter, and sprinkle with Italian seasoning and garlic powder.
Bake for 10-13 minutes.
Allow the rolls to cool slightly before serving with pizza sauce for dipping.
