Mustard-Maple Pork Tenderloin 33 Pork tenderloin is about as lean as it comes so it's a great healthy option, but it shouldn't be overcooked as it can dry out. Maple and mustard make a sweet-and-savory mahogany-colored sauce. A delicate note of sage gives it a wintery touch. Fresh thyme or rosemary also work if you prefer. Serve with barley, roasted squash and a Pinot Noir.
