Chicons au gratin is a traditional Belgian dish that is pure yummy delight during the winter as it provides comfort and warmth.
Try to avoid overly sweet baked ham (such as honey ham) as they may dominate the finished dish. I enjoy it with Prosciutto di Parma ham, except the slices of Parma ham often break as you wrap them around the Belgian endives. If you don't mind a less attractive dish, try it sometime. If you cannot find Belgian endives or do not like them, replace the Belgian endives with white celery or even cauliflower.
