Lightly flour a baking sheet. Roll out the refrigerated pizza dough, or your own homemade pizza crust.
Mix together shredded chicken, barbecue sauce, and diced onions. Spread the chicken mixture onto half your pizza dough. Lay spinach on top your chicken mixture.
Fold over the additional half of the pizza dough, covering the pizza fillings. Use a handheld pizza cutter to slice the piece into 1" wide strips. Cut one additional time the other direction, for strips about 1" by 4" so they are easy to pick up and serve.
With lightly floured hands, slowly twist your pizza dough and fillings and return to the baking sheet.
Combine melted butter, garlic powder, and Italian seasoning. Brush over pizza twists, then sprinkle with parmesan.
Bake at for 9-10 minutes, or until golden. Serve with marinara, if desired.
