Preheat your oven to 450°F (232°C).
Place the pre-made pizza crust on a baking sheet or pizza stone.
In a bowl, combine the shredded chicken with piri piri sauce. Mix well to coat the chicken evenly.
Brush the pizza crust with a thin layer of olive oil. This will help prevent the crust from becoming soggy.
Spread the piri piri-coated chicken evenly over the pizza crust.
Sprinkle the shredded mozzarella cheese over the chicken.
Arrange the sliced red onion, bell peppers, and black olives on top of the cheese.
Season the toppings with a pinch of salt and pepper.
Place the pizza in the preheated oven and bake for 12-15 minutes, or until the crust is golden and the cheese is melted and bubbly.
Once the pizza is out of the oven, sprinkle the chopped fresh cilantro on top for an extra burst of flavor.
