Wonderful and Different use for leftover Thanksgiving Turkey. Make sure to use really nicely "steeped" Turkey Stock for this recipe. Taste regularly for salt/pepper seasoning, if appropriate, add a little finely chopped SAGE.
Also, strongly recommend using finely chopped KALE rather thank Spinach, as the recipe calls for. Spinach leaves a particular flavor that can be unpleasant if the Spinach is frozen or NOT especially fresh. A different "green" would be better. DON'T FORGET THE PARMESAN!!
