01 - Let the pizza dough sit at room temperature for approximately 1 hour to make it easier to handle.
02 - Preheat the oven to 350°F. Line a baking sheet with aluminum foil and arrange bacon strips in a single layer. Bake for about 15 minutes until crisp. Drain on paper towels, then crumble and set aside.
03 - Season the chicken breasts with kosher salt, freshly ground black pepper, and garlic powder. Heat a large oven-safe skillet over medium-high heat and add olive oil. Place chicken seasoned side down and sear for 5 minutes. Flip, cook 1 more minute, then add just enough water to cover the bottom of the skillet. Transfer skillet to the oven and bake at 350°F for 17-20 minutes until chicken is cooked through (internal temperature 165°F). Remove from oven, allow to cool, and chop into bite-sized pieces.
04 - Increase the oven temperature to 400°F. Line a clean baking sheet with parchment paper. Lightly flour a large work surface. Divide rested pizza dough into 3 equal portions. Roll each into a large circle about 12 to 13 inches in diameter.
05 - Spread creamy Caesar dressing evenly over each dough round, leaving a 1-inch border. Sprinkle with approximately half the Parmesan cheese. Layer chopped chicken, crumbled bacon, green onions, and about three-quarters of the shredded Italian cheeses evenly among the portions.
06 - Fold edges of the dough slightly over the filling, then roll up tightly from the bottom to form a log. Pinch seams shut and arrange seam side down on prepared baking sheet.
07 - Brush the tops with beaten egg and sprinkle with remaining cheese. Bake at 400°F for about 20 minutes, or until golden brown and the cheese is melted.
08 - Allow bakes to cool slightly before slicing. Serve warm with a side salad or dipping sauce of choice.
