Cook the ravioli according to package instructions. If using fresh green beans, add them to the water at the same time as ravioli. If using frozen, add during the last 2 minutes of cooking. Drain the ravioli and green beans, reserving ½ cup of the pasta cooking water.
In a large bowl, combine the pesto with 2 tablespoons of the pasta cooking water. Add the cooked ravioli, green beans and chicken and toss gently, adding additional cooking water to the pan a little at a time to loosen the sauce if needed.
Divide the pasta among bowls and finish with cheese and parsley.
