Reduce the heat to medium and add the onions and celery. Sauté until the vegetables are just tender, about 5-7 minutes. Return the chicken to the pan and add the lima beans, pork, tomatoes, barbecue sauce, chicken stock, garlic and bay leaves. Bring the stew to a boil over high heat. Reduce the heat to low, cover the pan, and simmer gently until the chicken is nearly tender, about 35-45 minutes. Stir in the corn and simmer, uncovered, for 10 minutes. Skim any fat from the gravy. Add the Worcestershire, cayenne pepper, and season to taste with salt, black pepper and Tabasco. Sprinkle with the parsley. Enjoy!
