Pork tenderloin is about as lean as it comes so this is a great healthy option. This is indeed a one pan wonder dish and the pork comes out tender and moist. The maple and mustard make a sweet-and-savory mahogany-colored sauce that perfectly compliments the meat. A delicate note of sage gives it a wintery touch. This recipe is not only low-fat and healthy, but a wonderful inexpensive dish to entertain with during the holiday season.
