Whether you call it stuffing or dressing, this healthy sausage-and-chestnut stuffing recipe is a lightened-up version of the must-have holiday side. If you're an extra-moist-stuffing type, bake it covered for the full 50 minutes; if you like some crispy bits on top, follow the recipe as written: bake covered for about 30 minutes, then uncovered for an additional 20 minutes.
