Follow these straightforward steps to create your pepperoni pizzadillas:

1. Heat the Skillet: Preheat a non-stick skillet over medium heat.
2. Prepare the Tortillas: Lay out two tortillas on a clean surface.
3. Add Cheese: Sprinkle half of the shredded mozzarella evenly over each tortilla.
4. Layer Pepperoni: Add a generous layer of pepperoni slices on top of the cheese.
5. Optional Additions: If using, sprinkle chopped bell peppers, onions, or grated Parmesan cheese over the pepperoni.
6. Top with Cheese: Sprinkle the remaining mozzarella cheese over the pepperoni layer.
7. Cover with Tortilla: Place the second tortilla on each of the filled tortillas, creating a sandwich.
8. Apply Oil: Brush the top of each tortilla with olive oil or melted butter.
9. Cook Pizzadillas: Carefully place one pizzadilla into the hot skillet, oiled side down.
10. Cook Until Golden: Cook for approximately 3-4 minutes, or until the bottom is golden and crispy.
11. Flip: Gently flip the pizzadilla over using a spatula; cook for an additional 3-4 minutes, until the second side is also golden and the cheese melts.
12. Remove and Cut: Remove from the skillet and let it rest for a minute. Cut into wedges for easier serving.
13. Repeat: Repeat the process with the remaining ingredients to make the second pizzadilla.
14. Serve with Sauce: Serve warm with pizza sauce on the side for dipping.
