Preheat your oven to 475°F (245°C).
Prepare a baking sheet with parchment paper and set aside.
Roll out the pizza dough into a triangle shape.
Spread pizza sauce evenly over the dough.
Sprinkle shredded mozzarella cheese generously on top of the sauce.
Arrange pepperoni slices and diced bell peppers on top of the cheese.
Sprinkle grated Parmesan cheese over the top.
Drizzle a little olive oil over the top for added flavor and crispiness.
Bake in the preheated oven for 12-15 minutes, or until golden and crispy.
Remove from the oven and allow to cool for a few minutes before slicing.
Garnish with fresh basil leaves before serving.
