Directions:

1. In a large, deep skillet over medium-low heat, melt butter, then add flour. Cook, stirring constantly, until dark caramel colored, about 10 minutes.
2. Add onions, peppers, and celery, and stir until softened, about 5 minutes more. Stir in garlic and sausage, then season with Cajun seasoning, salt, and pepper. Stir in bay leaf, diced tomatoes, and chicken broth and bring to a boil. Reduce heat to low and simmer until thickened, stirring occasionally, about 1 hour.
