Instructions

  1. In a small bowl, stir together the sour cream, applesauce, breadcrumbs, horseradish, 1/4 cup chopped chives, and a generous amount of pepper. Cover and refrigerate.
  2. Meanwhile, in a large bowl, combine the beef, Worcestershire sauce and parsley; season with salt and pepper.
  3. Form into 4 patties, press your thumb into the center of each patty to prevent bulging during cooking, and coat each with olive oil.
  4. In a large skillet, cook the patties over high heat until the bottoms are well-browned, about 4 minutes. Flip, lower the heat and cook for 4 more minutes for medium-rare.
  5. Top each roll bottom with some of the watercress or cress sprouts, a beef patty, lots of horseradish sauce, and a sprinkling of chives. Crown with the roll's top.
