Traditionally, the meat includes sausage of some sort, often a smoked meat such as andouille, along with pork or chicken and seafood (less common), such as crawfish or shrimp. The vegetables are usually a sofrito-like mixture known as the “trinity” in Cajun cooking, consisting of onion, celery, and green bell pepper, though other vegetables such as okra, carrots, tomatoes, corn, chilies and garlic are also used.
