Uncover the dough and spread with the remainingn1/3 cup barbeque sauce, leaving a 3/4-inch border. Top with the chicken, Gouda, mozzarella and red onion. Slide the pizza (on the parchment) onto a pizza Peel or another inverted baking sheet, then slide onto the hot stone or baking sheet; bake until the cheese melts and the crust is golden, 20 to 25 minutes. Sprinkle with cilantro.
