Shrimp Creole
Shrimp creole is a dish of Louisiana Creole origin (French, and Spanish Heritage), consisting of cooked shrimp in a mixture of whole or diced tomatoes, the Holy trinity of onion, celery and bell pepper, spiced with hot pepper sauce and/or cayenne-based seasoning, and served over steamed or boiled white rice. The shrimp may be cooked in the mixture or cooked separately and added at the end. Other "creole" dishes may be made by substituting some other meat or seafood for the shrimp, or omitting the meat entirely.
