Easy Philly Cheese Steak Pizza

Step 1
Preheat oven to 400 degrees F (200 degrees C). Spray a skillet with cooking spray.

Step 2
Cook and stir beef sirloin in the prepared skillet over medium heat until browned on the outside and slightly pink in the middle, 3 to 4 minutes. Transfer sirloin to a plate.

Step 3
Spray the skillet with butter-flavored cooking spray. Add mushrooms, onion, and green bell pepper; cook and stir until just turning tender, about 5 minutes.

Step 4
Roll pizza dough onto a baking sheet and top with American cheese. Spoon mushroom mixture and sirloin over American cheese layer and top with Mexican cheese blend.

Step 5
Bake in the preheated oven until cheese is golden brown, 15 to 20 minutes.
