Pick over red beans, place into a large bowl, and pour in enough water to cover by several inches. Soak red beans overnight.
In a large soup pot, add the oil, garlic, green pepper, onion, celery. Sauté for a few minutes.
Drain and rinse red beans, add them to the soup pot with the vegetables and cover with 3 quarts of water and cook over medium to low heat.
Season pot with salt, black pepper, and Creole seasoning.
Reduce heat to low and cook until beans are tender, about 4 hours.
When beans are tender add the smoked turkey or andouille sausage that has been cut into bite size pieces to the soup pot. Stir to combine and let the flavors come together over low heat for 15-30 minutes, stirring occasionally.
