Roasting winter root vegetables caramelizes their natural sugars, producing a complex, toasty, and lightly sweet flavor. This recipe calls for a variety of winter vegetables, but you could use any combination, as long as you end up with about 12 cups total of bite-size pieces. This recipe can easily be cut in half if you're not cooking for a crowd. For added acidity, you could drizzle lightly with balsamic vinegar just before serving.
