Unroll crescent dough; separate into 8 triangles. Top with chicken, ham and cheese. Roll up tightly, starting at short side of each triangle.
Place, point sides down, on baking sheet.
Bake 12 to 15 min. or until golden brown. About 5 min. before roll-ups are done, cook gravy in saucepan on medium heat until heated through, stirring occasionally.
Serve roll-ups topped with gravy.
