This turkey supreme is made with easy creamy sauce, and it is a delicious way to use leftover sliced turkey. Serve the sauce and turkey over noodles, rice, or toast points. Add some extra flavor and color with some pimientos or cooked peas or carrots. Or saute a few tablespoons of green onions or shallots in the butter before you add the flour. Sauteed mushrooms would be an excellent addition as well. This creamy turkey would also be delicious served on toast as open-faced sandwiches or dice the turkey and serve it with the cream sauce over puff pastry shells. You can use chicken in the recipe as well.
