Serves 8
Juice of 1 large lemon
1 cup mayonnaise
1 cup buttermilk
½ cup sour cream
1½ teaspoons garlic powder
1½ teaspoons onion powder
6 ounces blue cheese, crumbled (about 1½ cups)
2 heads iceberg lettuce
10 slices bacon, cooked and crumbled
1 medium tomato, finely diced
Freshly ground pepper
In a medium mixing bowl, combine the lemon juice, mayonnaise, buttermilk, sour cream, garlic powder and onion powder. Whisk the mixture together until smooth. Add the cheese and mix just until blended. Chill in an airtight container in the refrigerator at least 2 hours before serving.
Core and quarter each head of lettuce. Serve a generous dollop of dressing over each lettuce wedge and top with the bacon and tomato. Season with pepper.
