Preheat oven to broil on high. Place a large cast-iron skillet over medium heat.
One skillet is warm, brush with olive oil using a party brush. Place a tortilla in the skillet and brush the outer edge with oil too.
Add pizza sauce to the center of the tortilla and use the back of a spoon to spread it over the tortilla. Leave the edges plain for the "crust". Break up provolone slice and place over sauce. Add mozzarella all over the pizza.
Add any additional toppings over cheese - like pepperoni, prosciutto, red peppers, or goat cheese.
At this point, the bottom of the tortilla should be crispy. You can use tongs to lift an edge up and check.
Once the tortilla bottom is crispy, place the skillet under broiler and cook for 60 to 90 seconds. Just long enough to get the cheese bubbly and crispy up the edges of the tortilla.
Carefully remove skillet from the oven. Use tongs to help transfer your pizza to a cutting board. Cut pizza into 4 or 6 slices and serve immediately.
