Step 1: Prepare the Dough

1. If using store-bought pizza dough, let it sit at room temperature for 20-30 minutes to make it easier to roll out.
2. If making homemade pizza dough, prepare it in advance and let it rise until doubled in size.
3. Lightly flour a clean surface and roll out the dough into a large rectangle, about ¼ inch thick.

Step 2: Make the Filling

1. In a large mixing bowl, combine the shredded chicken, crumbled bacon, mozzarella cheese, Parmesan cheese, Caesar dressing, garlic powder, black pepper, and salt.
2. Mix well until all ingredients are evenly coated in the dressing.

Step 3: Assemble the Chicken Bakes

1. Cut the rolled-out dough into 4 equal rectangles.
2. Spoon a generous amount of filling onto one side of each rectangle, leaving about ½ inch of space around the edges.
3. Fold the dough over the filling, pressing the edges together to seal. Use a fork to crimp the edges for extra security.
4. Place the chicken bakes seam-side down on a parchment-lined baking sheet.

Step 4: Add the Topping

1. In a small bowl, whisk the egg.
2. Brush the tops of each chicken bake with the egg wash to give them a golden, glossy finish.
3. Sprinkle Parmesan cheese over the top for extra flavor.

Step 5: Bake the Chicken Bakes

1. Preheat your oven to 375°F (190°C).
2. Bake the chicken bakes for 20-25 minutes, or until they are golden brown and crispy.
3. Let them cool slightly before serving.
