- Preheat the oven to 450 F. Line a baking sheet with parchment paper.  
- Sprinkle the chicken breasts with Italian seasoning, garlic salt, and onion salt.  
- Add it to a large saute pan over medium heat and cook for 12 to 15 minutes, flipping over half way through, until the chicken is an internal temperature of 165 F.  
- Let the chicken rest for 5 minutes, then cut it into bite sized pieces. 
- Cook bacon in a saute pan (or oven or airfryer) over medium heat until it reaches your desired crispiness. Crumble the bacon into small pieces.  
- Combine the ranch dressing and minced garlic in a small bowl. Set it aside.  
- Cut the pizza dough into 4 sections and roll each section into a circle, about 8 inches in size.  
- Top each circle with the ranch dressing, leaving a little space on the edges for sealing the calzones.  
- Sprinkle the mozzarella cheese evenly over the dressing.  
- Sprinkle chicken evenly over the cheese. Then sprinkle the bacon and the red onion.  
- Fold the dough circles in half covering the toppings completely. Pinch the edges sealed with your fingers.  
- Transfer the calzones to the prepared baking sheet.  
- Cut 2 to 3 slits in the top of each calzone to release the steam as they bake.  
- Beat the egg and water together in a small bowl. Brush the egg wash ontop of the calzones to help them turn golden brown.  
- Sprinkle the tops with garlic salt and parsley if desired.  
- Bake for about 15 minutes, or until the edges are golden and crispy and the insides are hot throughout.  
- Enjoy warm.
