1/2 pound chicken livers or duck livers, finely minced (optional)
Make dark roux by combining cooking oil and flour in heavy bottomed 6- to 8-quart saucepot, over low flame. Stir constantly using wooden spoon.
When roux is finished, stir in onion and allow to brown, leaving flame on low. Next, add andouille, celery, bell peppers and garlic. Add dirty rice mix and stir for five minutes to toast rice.
Stir in broth, allow mixture to come to a boil, cover with lid and simmer over low heat for 25 minutes. Before serving, season with minced green onion and parsley.
Note: If including chicken/duck livers, add livers and stir for an additional 4 minutes before adding broth.
