Instructions

  1. Make the dressing by whisking the mayo, ketchup, horseradish, Worcestershire sauce and salt to taste in a small bowl to smooth.
  2. Cook the bacon in a skillet over medium heat until crisp, then transfer with a slotted spoon to a paper towel lined plate to drain.
  3. Roughly chop the lettuce, then toss with some of the dressing in a serving bowl. Top with the tomatoes and scallions.
  4. Scatter the bacon and cheese over the salad; season with pepper and sprinkle with the parsley.
  5. Serve with more dressing on the side.
