Making Pepperoni Pizza Quesadillas is easy if you follow these straightforward steps:

1. Heat the Skillet: Preheat a large skillet over medium heat and add olive oil.
2. Prepare the Tortillas: Lay one tortilla flat on a clean surface.
3. Add Cheese: Sprinkle a generous amount of mozzarella cheese evenly over half of the tortilla.
4. Layer the Toppings: Add a layer of pepperoni on top of the cheese. If using, add bell peppers and olives.
5. Season: Sprinkle oregano and garlic powder over the toppings for extra flavor.
6. Fold the Tortilla: Carefully fold the tortilla in half to cover the fillings.
7. Cook the Quesadilla: Place the folded quesadilla in the hot skillet. Cook for about 3-4 minutes until the bottom is golden brown.
8. Flip and Cook: Carefully flip the quesadilla using a spatula. Cook for another 3-4 minutes until the cheese has melted and the other side is golden brown.
9. Remove and Slice: Remove the quesadilla from the skillet and place it on a cutting board. Allow it to cool for a minute, then slice into wedges.
