Instructions: Preheat oven to 450 degrees. Place the shell on an ungreased 12-inch nonstick pizza pan.

To assemble the pizza, spread the pizza sauce over the shell, leaving a 1-inch border around the rim. Sprinkle with half of the cheese.

Arrange the cooked sausage on top of the cheese, covering evenly. Top with onion and mushrooms slices. Sprinkle evenly with oregano, basil, and red pepper flakes (if using). Top with remaining cheese.

Bake for 13 to 15 minutes, until the crust is crisp and the cheese is melted and browned. Cut into 6 wedges.
