Open and unroll the crescent dough and separate into 8 triangles, placing on the prepared baking sheet. Spoon about 2 tablespoonfuls of chicken mixture onto the middle of each dough triangle, dividing the mixture evenly between the 8 triangles. For each roll, bring the 3 points of the triangle together on top of the mixture, gently twisting and sealing into a knot (you will still be able to see the filling). If desired, brush dough with beaten egg white.
