This looks like a combination of Raclette(melted cheese with potatoes, onions and pickles) and Pierrade (grilled meats and vegetables). We love both of these events from the Haute Savoie region of France. In truth, they are not usually served together in France or Switzerland, but use the same type of heat source, so the combo does work. One should be warned that the cheese has a mild taste but a strong odor and unappetizing appearance.
Simply Fantastic! Love the recipe Mark, keep up the good work. :)
