The beans can also be made on the stovetop over medium heat, but the cooking time will be shorter since it will cook over direct heat. Cook the beans until the broth is reduced to 1/4 to 1/3 cup before removing from the heat. The beans can be made up to 2 days in advance and stored in an airtight container in the refrigerator. When ready to serve gently reheat on the grill or stovetop.
