Preheat the Oven: Preheat your oven to 400°F (200°C) and prepare a baking sheet by lining it with parchment paper or lightly greasing it with olive oil.

Dust the Surface: Lightly dust your work surface with all-purpose flour, then roll the pizza dough into a rectangle about 1/4 inch thick.

Spread the Ranch Dressing: Evenly spread the ranch dressing over the dough, leaving a small border around the edges.

Layer the Chicken and Bacon: Distribute the diced or shredded chicken and chopped bacon evenly over the ranch dressing.

Add Cheese and Green Onions: Sprinkle the shredded mozzarella cheese over the top of the chicken and bacon, then add chopped green onions if using.

Roll the Dough: Starting from one long side, carefully roll the dough into a log, keeping the filling inside and the roll tight.

Seal the Edges: Pinch the seams and ends of the dough to seal the stromboli, then place it seam-side down on the prepared baking sheet.

Brush with Olive Oil: Lightly brush the top of the stromboli with olive oil, then sprinkle grated Parmesan cheese over it.

Cut Slits for Steam: Use a sharp knife to cut a few small slits in the top of the stromboli to allow steam to escape.

Bake: Bake the stromboli for 20-25 minutes, or until the crust is golden brown and the cheese is bubbly.

Rest and Slice: Let the stromboli rest for a few minutes after baking, then slice it into thick pieces and serve warm.
