Preheat oven to 375°F. In large bowl, combine first 3 ingredients; fold in chicken.
Unroll crescent dough on a flat surface, separating triangle sections. Divide prepared mixture onto widest part of each triangle; roll up as directed on package, pinching open edges or folding them to the top to seal in filling. Place on greased 11x17-inch baking sheet. Bake 18-20 minutes or until golden brown.
