This is a Louisiana favorite. Many years ago, red beans and rice were served for lunch in New Orlean’s grammar schools.
Saute onion, green pepper, and garlic in oil. Add beans (drained or not, depending on how much liquid you want for the rice), salt, and peppers. Add sausage, cut in large pieces. Simmer for 30 minutes. Serve over fluffy white rice, with a salad and French bread.
