Sort and rinse beans, then soak in water overnight.
Add olive oil to skillet, then sautee onion, bell pepper, garlic, and celery for 3 to 4 minutes.
Rinse beans. Pour into a large pot. Add 6 cups water and the cooked vegetables. Add seasonings (bay leaves, cayenne pepper, thyme, sage, parsley, and Cajun seasoning). Bring this to a boil. Reduce heat to medium-low and simmer 2-1/2 hours.
Add sausage into beans, and simmer 30 minutes.
While the beans are simmering, prepare the rice. In a saucepan, boil water and rice. Reduce heat to low and cover for 20 minutes. Or use a rice cooker for this step. Serve the red beans over steamed white rice.
Note: Don't forget to soak the beans overnight to soften them and remove some of the indigestible complex sugars that cause gas. You really don't want to forget this step!
