In a large 12-inch skillet, cook sausage over medium heat, approximately 10 minutes or until no longer pink.  Drain and discard pan juices.  Cut sausage links in half.  Return links to the skillet.  Add apple wedges.  Then sprinkle with the brown sugar, lemon juice, and salt and pepper.  Cover and cook over medium-low heat for 10 - 15 minutes or until apples are just tender.  Stir once or twice while cooking.
