This light, tasty casserole is a good way to use left-over holiday turkey. It's a healthy alternative to those traditional post-holiday meals of gravy, stuffing and cranberry sauce. This is the recipe as written, but since I find the sage to be a little overpowering, I use less. Sometimes I substitute the sage for dill and add chopped garlic. The beauty of this recipe is that you can flavor it almost any way that you want to; make it spicy or not, depending on your tastes.
