Place a large sheet of heavy-duty foil onto a baking sheet. Spray with cooking spray and unroll the pizza crust over the foil. Press the dough into a 10x14-inch rectangle.
Place the foil directly on the grill. Cook uncovered for 3 to 5 minutes or until the bottom of the crust is golden.
Using heat-resistant gloves or a large spatula, remove from the grill. Carefully flip the pizza crust over on the foil.
Spread pizza sauce over the crust, followed by the cheese and pepperoni. Place back onto the grill and cook covered for 3-5 more minutes until crust is golden and cheese is melted.
Notes
Leftovers will keep in the refrigerator for 3 days. Reheat in the air fryer or in the microwave.
