In a heavy Dutch oven, saute bacon, pork and livers until very brown. Let the meat stick to the skillet a bit before stirring. Add onion, bell pepper, celery and garlic and cook until they are wilted.
Add chicken broth, bay leaf, thyme, cayenne pepper, salt and pepper. Simmer for 30 minutes. Remove bay leaf. Add rice and toss the mixture until rice is hot. Stir in green onions and parsley. Adjust seasonings. (Serves 8 to 10)
