You wont have any trouble getting your family to eat their greens when you serve this hot and cheesy casserole. A great pick to serve with your holiday feast, this casserole, which only takes 45 minutes from oven to table, also makes a satisfying side dish for a weeknight dinner. Just pair it with grilled chicken or a steak. Cook onions and garlic together, then add kale and collards and allow them to wilt in the heat of the skillet. Stir in cream cheese, fontina, and seasonings, pour into a baking dish, top with fresh breadcrumbs, and bake. Look for pre-chopped greens in the produce section of your grocery store; convenience products can go a long way in cutting down on prep time. To make this casserole in advance, cool the mixture in baking dish to room temperature, cover with aluminum foil and refrigerate. Reheat, covered, in a low oven (250f to 300f) until hot and bubbly, then uncover and bake until the bread crumb top browns.
