I love anything with gruyere and can't wait to try this dish!! From Cooking Light 11/08...."Gruyère's nutty, earthy flavor is a nice match for subtle cauliflower, and crisp breadcrumbs add texture. Substitute broccoli for the cauliflower, if you prefer. You can prepare all the elements for the dish a day ahead, if necessary. Refrigerate the sauce, the cauliflower, and the breadcrumb mixture separately, and simply assemble before baking."
