Preheat your oven to 375°F (190°C).
In a mixing bowl, combine shredded turkey, cranberry sauce, cream cheese, rosemary, and cheddar cheese.
Unroll the crescent roll dough and separate it into triangles.
Arrange the triangles in a circle on a baking sheet, overlapping them slightly.
Spoon the turkey mixture onto the wide ends of the triangles.
Fold the pointed ends of the triangles over the filling and tuck them underneath.
Brush the dough with beaten egg to achieve a golden finish.
Bake for 25-30 minutes or until golden brown.
Let it cool slightly before slicing and serving.
