Ingredients
3/4 cup sour cream
1/4 cup unsweetened applesauce
1/4 cup plain breadcrumbs
1/4 cup prepared horseradish
1/4 cup chives, chopped, plus more for sprinkling
Salt and pepper
2 pounds ground beef sirloin
1/4 cup Worcestershire sauce (eyeball it)
1/4 cup curly leaf parsley, finely chopped
1 tablespoon extra virgin olive oil (EVOO)
4 seeded Laiser rolls, split
1 bunch watercress
Directions
In a small bowl, stir together the sour cream, applesauce, breadcrumbs, horseradish, 1/4 cup chives and a generous amount of pepper. Cover and refrigerate. Meanwhile, in a large bowl, combine the beef, Worcestershire sauce and parsley; season with salt and pepper. Form into four patties and coat each with the EVOO. 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. Top each roll bottom with some of the watercress, a beef patty, lots of horseradish sauce, a sprinkling of chives and a roll top.
