Many Thanksgiving stuffings rely on bread; some of our most favorite and traditional recipes include cubed white bread or bread crumbs. But you don't have to use white bread. Some people substitute breads such as challah or brioche, French baguette, potato bread, or sourdough boule -- or a mix of a few different stale breads.
Some Thanksgiving menus feature stuffing made with leftover breakfast: stale bagels. Plain, whole wheat, rye, pumpernickel or even an everything bagel could work. Season as you might a traditional turkey stuffing, with aromatic vegetables (onions and celery), butter and herbs such as parsley, sage, rosemary and thyme [sources: Balsley, Taste of Home].
