Preheat your oven to 400 degrees Fahrenheit.
Spread the tomato sauce evenly over the pizza dough or crust.
Sprinkle the cheese evenly over the sauce.
Add the pepperoni slices evenly on top of the cheese.
Bake the pizza for 30 minutes until the cheese is melted and bubbly and the crust is golden brown.
Remove from the oven, let cool slightly, then slice and serve.
