Root Vegetable Gratin
Serves 4 to 6 (easily doubled).
Note: Use any mix of root vegetables you like and have available, but make sure they are sliced super thin. You can make this in advance and bake it right up to the step before adding the cheese topping. Do that topping before serving to be sure the gratin is bubbly, crisp and hot. Panko is larger and lighter than the traditional breadcrumb, which could be substituted. From Beth Dooley.
