1. Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
2. Roll out the pizza dough on a lightly floured surface, aiming for a rectangle about 12×8 inches in size.
3. Sprinkle the mozzarella cheese evenly over the dough, leaving a small border around the edges.
4. Layer the pepperoni slices over the cheese, ensuring even coverage.
5. Starting from one of the long sides, carefully roll the dough into a tight log, pinching the seam to seal.
6. Cut the roll into 1-inch segments and place them cut-side up on the prepared baking sheet.
7. In a small bowl, mix together the Parmesan cheese, Italian seasoning, and garlic powder, and sprinkle over the roll-ups.
8. Bake for 12-15 minutes, or until golden brown and the cheese is bubbly.
9. Serve warm with marinara sauce for dipping, and garnish with fresh basil if desired.

These roll-ups are as straightforward as they sound, but don’t be afraid to get creative. If you’re feeling adventurous, try adding some chopped olives or mushrooms for extra flavor—a tip I learned from countless kitchen experiments.
