Step 1

Adjust oven rack to the middle position and preheat broiler to high

Step 2

Heat a large broiler-safe nonstick skillet over medium heat, brush the oil on the bottom and add the flour tortilla "bubbly-side" down to start crisping it before it goes in the oven

Step 3

Almost immediately, build the pizza right in the pan

Step 4

For the white hot crispy tortilla pizza, spread the ricotta cheese on the tortilla, then top with the shredded mozzarella, making sure the cheese goes all the way to the edge and beyond! Sprinkle with the Parmesan cheese, then scatter the mozzarella slices and sage leaves across the top

Step 5

For the crispy bar-style tortilla pizza (shown in photo), scatter the tomatoes across the tortilla, then top with the shredded mozzarella, making sure the cheese goes all the way to the edge and beyond! Using a fork, disperse the giardiniera over the cheese, then scatter the pepperoni slices and sage leaves (if using) across the top

Step 6

Place the skillet under the broiler and cook for about 4 to 5 minutes or until the cheese is golden brown and melty

Step 7

Slide the pizza onto a cutting board and cut into slices
