Melt unsalted butter in a skillet over medium-high heat. Add julienned red onions and sauté for approximately six minutes until caramelized and tender. Remove from heat and set aside to cool.

Roll out fresh pizza dough on a parchment-lined surface into a large rectangle approximately 6 mm thick, ensuring even stretching to maintain structure for rolling.
03 -
Arrange provolone cheese slices along the center of the dough, overlapping slightly to create a consistent cheesy layer. Leave margins along edges to allow sealing.
04 -
In a mixing bowl, combine shredded rotisserie chicken, sautéed onions, and barbecue sauce. Toss until chicken is thoroughly coated, forming a glossy, sticky filling.
05 -
Evenly distribute the chicken mixture over the cheese layer. Gently press down to compact filling and prevent shifting during rolling.
06 -
Starting from one long edge, carefully roll the dough over the filling using parchment paper as a guide. Pinch seams to seal tightly and tuck both ends underneath to secure filling containment.

Brush the exterior surface of the rolled stromboli with beaten egg for a glossy finish. Sprinkle Italian seasoning and grated Parmesan evenly on top. Score five shallow diagonal slits to allow steam release during baking.
08 -
Transfer stromboli to a baking sheet and bake in a preheated oven at 190°C (375°F) for 20 to 25 minutes, or until crust turns golden brown. Remove from oven and allow to cool for five minutes before slicing. Serve with additional barbecue sauce for dipping.
