Paint the dough with sauce and sprinkle with additional Parmesan cheese, if desired. Spread 1/4 of the mushroom mixture on top of the sauce and sprinkle with the cooked sausage (if using). Then, arrange slices of the bell peppers, green chile, cheese and tomato over the mushrooms. Top with the fresh cilantro leaves.
Bake the pizza for 12 to 15 minutes. Repeat with the remaining dough and toppings. Serve.
