Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine the shredded turkey, cranberry sauce, cream cheese, shredded mozzarella, thyme, and garlic powder.
Unroll the crescent roll dough and lay it out into a circle on a baking sheet lined with parchment paper.
Spoon the turkey and cranberry mixture onto the center of the dough circle.
Fold the points of the crescent dough over the filling, pinching edges to seal tightly.
Brush the tops of the dough with the beaten egg.
Bake in the preheated oven for 20-25 minutes or until golden brown.
Remove from the oven and let cool for 5 minutes before slicing.
