I don't know if this is the exact recipe from the restaurant you mentioned, but here is one way to fix this soup. Andouille Sausage and Red Bean Soup

1 tbsp olive oil
1/2 cup diced bacon
1 1/2 cups chopped onions
1/4 cup chopped green bell peppers
1 tbsp minced garlic
4 bay leaves
6 oz sliced andouille sausage
1 small smoked ham hock (5-6oz)
2 cups dried red kidney beans, soaked overnight
1 tsp Creole seasoning
1 tsp Worcestershire sauce
2 quarts Basic Chicken Stock
1 tsp salt
1 1/2 cups cooked long-grain white rice, warm
6 tbsp chopped green onions

1. Heat the oil in a large heavy pot over high heat. Add the bacon and saute for 2 minutes. Add the
onions, bell peppers, garlic, bay leaves, andouille, and ham hock and cook, stirring, for 2 minutes.

2. Add the beans and cook for 2 minutes. Stir in the Creole seasoning, Worcestershire sauce, and
the stock, and bring to a boil. Reduce the heat to medium and cook for 1 hour, stirring occaisionally.
Add the salt, cover the pot, and cook for 15 minutes. Turn off the heat and allow the pot to sit,
covered, for about 20 minutes. Discard the ham hock.

3. To serve, ladle a generous cup of the soup into each of 6 bowls. Top each serving with 1/4 cup
rice and sprinkle each with 1 tablespoon of the green onions.

Makes 7 cups, 6 hearty first-course servings.
