Creating Flaky Pepperoni Pizza Rolls with Mozzarella and Herbs is straightforward. Follow these simple steps:

1. Preheat Your Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Prepare the Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry sheets to smooth them out.
3. Cut the Pastry: Using a knife or pizza cutter, cut each sheet into squares (about 4×4 inches).
4. Add the Filling: Place a small amount of mozzarella cheese and a few slices of pepperoni in the center of each square.
5. Season: Sprinkle Italian herbs, salt, and pepper over the filling for added flavor.
6. Fold the Pastry: Fold the corners of each square toward the center, creating a pocket. Press the edges to seal.
7. Apply Egg Wash: Beat the egg in a small bowl. Brush the egg wash over each pocket to give them a golden color when baked.
8. Bake: Place the filled pastry pockets on the prepared baking sheet. Bake for 20-25 minutes or until golden brown and flaky.
9. Cool: Remove from the oven and allow them to cool slightly before serving.
