Creating Pepperoni Pizza Quesadillas is simple and enjoyable. Just follow these easy steps:

1. Prepare Ingredients: Gather all the ingredients and set them out for quick access.
2. Heat Skillet: Preheat a skillet over medium heat and lightly grease with cooking spray or olive oil.
3. Layer Quesadilla: On one tortilla, spread a thin layer of pizza sauce. Then sprinkle half of the mozzarella cheese evenly over the sauce.
4. Add Toppings: Place an even layer of sliced pepperoni on top of the cheese, followed by a sprinkle of Parmesan cheese and Italian seasoning, if desired.
5. Cover with Cheese: Add the remaining mozzarella cheese over the pepperoni, then place a second tortilla on top to close the quesadilla.
6. Cook Quesadilla: Carefully transfer the quesadilla to the hot skillet. Cook for about 3-4 minutes until the bottom is golden brown and crispy.
7. Flip Cautiously: Using a spatula, carefully flip the quesadilla and cook the other side for another 3-4 minutes until it is golden brown and the cheese has melted.
8. Remove and Slice: Once cooked, remove the quesadilla from the skillet and let it cool for a minute. Slice it into wedges with a pizza cutter.
9. Repeat: Repeat the process with the remaining tortillas and ingredients.
10. Serve: Serve warm with extra pizza sauce on the side for dipping.

Be sure to watch the quesadillas closely, as cooking times may vary based on your stove. Adjust the heat as needed to avoid burning them.
