Prepare Your Ingredients: Put the tortillas on a flat table. Take a spoonful of pizza sauce and spread it over one side of each tortilla.
Add Cheese and Pepperoni: Scatter around 1/4 cup of shredded mozzarella on top of the sauce. Then, evenly place the turkey pepperoni slices over the cheese layer.
Season Your Fillings: Sprinkle a tiny bit of garlic powder and Italian seasoning over the fillings. Then, fold each tortilla in half to hold everything together.
Cook Your Quesadillas: Warm a dab of butter or pour some olive oil in a pan over medium heat. Add one or two folded tortillas to the pan, depending on the size.
Flip and Finish Cooking: Flip after 2-3 minutes per side, cooking until the outside is golden and the cheese has melted inside.
Serve and Enjoy: Take off the heat, give it a minute to cool, then cut into wedges. Enjoy warm with extra pizza sauce on the side for dipping.
