• In a large nonstick skillet over medium-high heat on the stove, warm the oil. Add the onion and cook until lightly browned and softened, 8 to 9 minutes, stirring occasionally. Stir in the bell peppers and cumin and cook until the peppers are crisp tender, about 3 minutes more. Remove from the heat and season with the salt.
• Cover one ball of pizza dough with a kitchen towel. On a lightly floured surface roll the other ball into a 12-inch-diameter circle. Generously dust a pizza peel (or rimless baking sheet) with flour, and then transfer the dough to the peel.
• Spread the dough with half of the sauce, leaving a ¾-inch border around the edge. Top with half of the onion-bell pepper mixture, half of the chicken, and half of the cheese.
• Carefully slide the pizza onto the pizza stone, close the lid, and cook over direct medium-high heat until the crust is browned on the bottom and the cheese is melted, 9 to 11 minutes, rotating the pizza once. Transfer to a cutting board and let stand for 3 to 5 minutes before cutting into wedges. Make another pizza with the remaining dough ball, toppings, and cheese.
