Preheat the oven to 350 and then season both sides of the tenderloin with dried sage, rosemary, salt and pepper, to taste.
Place the prepared turkey in a roasting pan and cover and then roast for approximately 40 minutes or until the juices run clear. Take out of roasting pan and place on cutting board.
Tent with aluminum foil and all the meat to rest for 5 to 10 minutes before slicing. Slice the tenderloin into 1 1/2 to 2-inch slices and serve.

Notes
Allow the meat to set for 15 minutes before carving. This will help it to reabsorb some of the flavorful juices.
