Rub the meat with the mustard, sprinkle with herbs and salt and lay in a roasting dish. Fry the bacon in the butter and pour over meat.
Roast in a pre-heated oven at 400 degrees F for approximately 90 minutes until juices run clear and meat is no longer pink (use a meat thermometer to check correct internal temperature is reached). Periodically pour water over roast (about 3/4 cup).
In the meantime, chop the carrot, parsley and onion. Add wine and vegetables to roast after 40 minutes.
Serve with German potato dumplings (Kartoffelklößen) and German red cabbage (Rotkohl).
