In a saucepan, combine jar contents with 3 ½ cups water and 1 tbsp oil or butter.
Bring to a boil, then reduce heat, cover, and simmer until rice and beans are tender (about 40–45 minutes).
For creamier, New Orleans–style texture: stir in an extra splash of water near the end and mash a few beans with the back of a spoon.
Optional: stir in ½ lb smoked sausage or ham while cooking for a full meal.
