Preheat oven to 375º. Unroll crescent dough and separate into 16 triangles. With wide ends of triangles toward the center, arrange in a circle. Corners of wide ends will touch and points will extend 1-inch beyond the edge. Arrange remaining 8 triangles in center matching the wide ends. Fold together mayonnaise, mustard and black pepper in a bowl. Add turkey, celery, parsley and Festival Blend to batter. Scoop filing over seams of dough, forming a circle. Beginning in the center, lift one dough triangle, slightly overlapping to form wreath. Tuck last end under first. Separate egg, beat egg white lightly, brush over dough. Bake 25-30 minutes or until golden brown. Slice and serve.
