From the Marlboro Country Cookbook....something to perk up the standard side of mashed or baked potatoes. Thinly sliced red, white and sweet potatoes are layered and baked with butter and fresh grated Parmesan (I sometimes substitute Asiago cheese). This particular cookbook is perhaps my favorite. Very rich, western and south-western style recipes. If you can get your hands on one (through E-Bay, a yard sale or otherwise) I highly recommend you add it to your cookbook collection!
