Yes, using a store-bought rotisserie chicken is a quick and easy way to make this recipe. Remove the skin and pull the meat off the bones. Make sure to use both the dark and the white meat. Shred the meat into bite-size pieces, sprinkle with some Creole seasoning and set it aside. Follow the recipe instructions (without browning the chicken first). After the gravy has simmered for about 30 minutes, add the cooked, shredded chicken. Let the shredded chicken simmer in the gravy for about 15 minutes before you finish with the green onions, parsley and butter.
