Preheat your oven to 400°F and lightly spray a sheet pan with nonstick cooking spray.
Lightly flour a clean surface and roll out the Pillsbury pizza crust until it fits your sheet pan. Transfer the dough to the prepared pan, gently stretching it to the edges if needed.
Bake the crust for 10 minutes to par-bake it. Remove it from the oven.
Evenly spread the pizza sauce over the crust, then sprinkle most of the shredded mozzarella cheese over the sauce.
Arrange the pepperoni slices in an even layer over the cheese, then top with the remaining mozzarella and Italian seasoning
Return the pizza to the oven and bake for 7 minutes, or until the cheese is fully melted and bubbly.
Remove the pizza from the oven and let it cool for 2–3 minutes before slicing. Serve hot and enjoy!
