Making Spicy Chili Garlic Chicken Pizza is straightforward if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 475°F (245°C) to ensure a crispy crust.
2. Prepare the Dough: Roll out the pre-made pizza dough on a floured surface to your desired thickness. Transfer it to a pizza stone or baking sheet.
3. Mix the Chicken: In a bowl, combine the shredded chicken with chili garlic sauce. Toss until well coated.
4. Add Olive Oil: Drizzle olive oil over the rolled-out dough to enhance flavor and prevent sogginess.
5. Spread Chicken Mixture: Evenly distribute the chili garlic chicken over the pizza dough.
6. Add Vegetables: Scatter the sliced bell peppers and red onion over the chicken for an added crunch.
7. Top with Cheese: Sprinkle shredded mozzarella cheese generously over the entire pizza, covering the toppings.
8. Season: Sprinkle dried oregano and crushed red pepper flakes to enhance the flavors.
9. Bake the Pizza: Place the pizza in the preheated oven and bake for 15-20 minutes or until the crust is golden brown and the cheese is bubbly.
10. Garnish and Serve: Once baked, remove the pizza from the oven and let it cool for a few minutes. Garnish with fresh cilantro or parsley before slicing.

These steps will guide you in creating a mouthwatering Spicy Chili Garlic Chicken Pizza that is sure to impress.
