1/4 cup plus 2 tablespoons shredded mozzarella cheese
1 chicken breast, cooked and shredded
1/2 purple onion, chopped
1/4 cup plus 2 tablespoons shredded Romano cheese
Heat oven to 400 degrees F.
Unroll pizza dough on clean work surface. Pat out to 15-in x 11-in. rectangle; cut lengthwise in half, then cut each piece crosswise into thirds.
Top dough rectangles with 1 tablespoons barbecue sauce. Layer 1 tablespoon mozzarella, about 1/4 cup shredded chicken (really loosely packed), 1 1/2 tablespoons chopped onion, and 1 tablespoon Romano cheese. Drizzle 1 tablespoon over filling and fold in half.
Seal edges with fork. If needed, dampen edges to make them stick together.
Place on baking sheet sprayed with cooking spray. Bake 15 minutes or until golden brown.
