Preheat the oven to 375 degrees F. Line a baking sheet with parchment and/or spray with cooking spray. 

In a medium-sized bowl, add the chicken, pizza sauce, mozzarella, and 1/4 cup of parmesan cheese. Mix well to combine. 

Spread dough onto the cookie sheet and shape into a large rectangle (it should cover most of the baking sheet). 

Add the chicken mixture lengthwise down the center of the dough, about 4 inches thick, from end to end. 

Make cuts 1 inch apart on each side of the rectangle, just to the edge of the filling. Alternating from side to side, fold crust strips of dough at an angle across the filling. It’s ok if it overlaps some.

Microwave butter in a small bowl for 20-30 seconds, or until melted. Stir in onion powder and Italian seasoning. Brush mixture on top of braided dough. Sprinkle with remaining 1 Tbsp parmesan cheese. 

Bake for 20-25 minutes or until the dough is golden brown. Heat remaining pizza sauce in the microwave to serve with Stromboli for dipping.
