Unroll crescent dough; separate into 16 triangles. Arrange in 11-inch circle on foil-covered baking sheet, with short sides of triangles overlapping in centre and points of triangles toward outside. (There should be a 5-inch diameter opening in centre of circle.) Spoon cheese mixture onto dough near centre of circle. Bring outside points of triangles up over filling, then tuck under dough in centre of ring to cover filling.
