Cook ravioli according to package instructions and set aside.
Cut up rotisserie chicken, using as much as desired. Cut broccoli into bite-size pieces or smaller.
In pan over medium heat, heat chicken through. Add garlic powder and onion powder. Deglaze pan with 1 cup chicken broth then add alfredo sauce and broccoli.
Pour in remaining broth if sauce is too thick. Stir in cooked ravioli and heat through 2-3 minutes.
