Preheat oven to 375 degrees. In a bowl, combine the first nine ingredients & 6 ounces of the grated cheese (saving the remainder for garnish). Mix well.
Unroll the crescent roll dough & separate into 16 triangles. Arrange the triangles in a circle with the wide ends of the triangles overlapping in the center and the points facing the outer edge on a pizza pan or round baking stone. With a dough roller, flatten wide part of triangles to accommodate more chicken filling space. Scoop the filling onto the widest end of each triangle. Bring the outside points of the triangles up over the filling and tuck under the wide ends of the triangles.
Arrange the ring on the pan to resemble a curvy snake. Insert a roasted red pepper for a tongue & other peppers between each pastry triangle. Add slices of green olives for the eyes.
Brush the pastry with the egg white. Bake for 20-25 minutes or until deep golden brown. Remove from oven & sprinkle with remaining cheese.
