Creating Mozzarella Pepperoni Croissant Rolls is a straightforward process that anyone can master. Follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C). If using parchment paper, line a baking sheet with it or spray the sheet with cooking spray.
2. Prepare Croissant Dough: Open the package of croissant dough and carefully unroll it on a clean surface. Separate the dough into individual triangles.
3. Add Cheese and Pepperoni: On the wide end of each triangle, sprinkle a generous amount of shredded mozzarella cheese and place a few slices of pepperoni on top.
4. Season (Optional): If desired, sprinkle Italian seasoning over the cheese and pepperoni for added flavor.
5. Roll Up: Starting from the wide end, gently roll up each triangle toward the pointed end, creating a crescent shape. Ensure the filling is tucked inside.
6. Prepare Egg Wash: In a small bowl, beat the egg to make an egg wash. Brush the tops of the rolled croissants with the egg wash to achieve a golden-brown color when baked.
7. Bake: Place the rolls on the prepared baking sheet and bake in the preheated oven for about 15-20 minutes, or until they are golden and flaky.
8. Cool Slightly: Once baked, remove the rolls from the oven and let them cool for a few minutes on a wire rack.
9. Serve Warm: These rolls are best enjoyed warm!
