Preheat your oven to 425°F (220°C). If using a pizza stone, place it in the oven while it preheats.
In a medium bowl, toss the chicken pieces with olive oil, chili powder, cumin, paprika, garlic powder, salt, and pepper until evenly coated.
Heat a skillet over medium-high heat. Add the seasoned chicken and cook for about 5-7 minutes, or until cooked through. Remove chicken from skillet and set aside.
In the same skillet, add the sliced onion and bell pepper. Cook for 5-7 minutes, stirring occasionally, until slightly softened.
Stretch or roll out the pizza dough to your desired thickness and place it on a pizza peel dusted with cornmeal or directly onto a baking sheet lined with parchment paper.
Spread the salsa evenly over the pizza dough, leaving a small border for the crust.
Distribute the cooked chicken and sautéed vegetables evenly over the salsa.
Sprinkle both the Monterey Jack and cheddar cheeses over the toppings.
Carefully transfer the pizza to the preheated oven (or onto the hot pizza stone).
Bake for 12-18 minutes, or until the crust is golden brown and the cheese is melted and bubbly.
Remove from oven, let it cool slightly, then slice and serve. Garnish with sour cream and cilantro if desired.
Notes
This pizza is delicious on its own, but a dollop of sour cream and some fresh cilantro really elevate the flavors!
