Mozzarella and mashed potato pie. Great twist on mashed potatoes - The southern junior league cookbook. Looks yummy for a special meal. Maybe only one layer of mozzarella though. Can top tomatoes with just parm.
Not healthy, but maybe a yummy side dish on Thanksgiving! Creamed Corn Casserole -- so good you'll want to scrape the dish completely clean to get every last bit of caramelized goodness from the corners!
