This is my adaptation of an old recipe from Bon Appetit. Because the chicken has to marinate, and because I think it's best with dried rather than canned beans, it requires advance planning. But it's really quite simple and very good. It can be made with other chicken parts, but I like it best with chicken breasts. Note: Preparation time does not include soaking and cooking time for dried beans, but does include three hours for marinating chicken.
