Rockin' Rueben Ring

Preheat oven 350 F. Unroll crescent dough; separate into 16 triangles. With wide ends of triangles toward the center, arrange 8 triangles in a circle on large round stone. Corners of wide ends will touch & points will extend 1" beyond edge of stone. Match wide end of each remaining triangle; seal seams. Chop corned beef and add to onion & parsley. Mix swiss cheese, sauerkraut, dressing & pepper and add to meat mixture. Scoop mixture onto arranged crescent rolls. Beginning in center, lift the dough over the mixture creating a ring. Lightly brush egg white over dough. Bake 20-25 minutes, until golden brown.
