Spray the bottom of a non-stick skillet with cooking spray and preheat. When the pan is fairly hot place 1 Flour Tortilla in the pan.
Fairly quickly (because you want to get everything on before the bottom starts to brown) spread on a few tablespoons of sauce. Then add a layer of Pepperoni (and anything else you like). Then top with shredded cheese.
Top it off with the second flour tortilla.
Just like any other quesadilla or grilled cheese let it brown then flip it over.
After both sides are browned and the insides are hot and melted take the “pizzas” out to cool. Once cooled slice in ¼ like a pizza and wrap snugly with plastic wrap or aluminum foil.
