Preheat the oven to 375°F (190°C).
In a large bowl, mix the shredded turkey, cranberry sauce, cream cheese, dried thyme, salt, and pepper until combined.
Unroll the crescent roll dough on a baking sheet lined with parchment paper.
Arrange the crescent roll triangles in a circular pattern, overlapping edges slightly to form a ring.
Spoon the turkey mixture into the center of the dough ring, spreading it evenly.
Fold the points of the dough over the filling toward the center, pinching to seal.
Brush the top of the dough with the beaten egg to give it a golden color as it bakes.
Bake in the preheated oven for 25-30 minutes or until golden brown.
Remove from the oven and let it cool slightly before slicing.
