                Set oven to 190°C and line a baking sheet with parchment paper.

                On a floured work surface, roll the pizza dough into a 30x40 cm rectangle, maintaining an even thickness.
              
              
              
                03 - 
                In a medium bowl, thoroughly mix the chicken, ham, Swiss cheese, provolone cheese, garlic powder, onion powder, black pepper, salt, dried oregano, and dried thyme until evenly blended.

                Evenly coat the rolled dough with Dijon mustard, leaving a 2.5 cm border along all edges.
              
              
              
                05 - 
                Distribute the chicken and cheese mixture evenly over the mustard-coated dough, ensuring an even layer without overfilling.
              
              
              
                06 - 
                From one long edge, carefully roll the dough over the filling, tucking in sides while rolling. Pinch seams firmly to seal.
              
              
              
                07 - 
                Place the rolled loaf seam-side down on the prepared baking sheet. Brush with beaten egg for a golden finish. Cut a few slits on top to allow steam to escape.
