In a small bowl, whisk together mayonnaise, sour cream, Worcestershire sauce, vinegar, parsley, chives and dill. Add buttermilk until the dressing reaches desired consistency. Season with salt and pepper, to taste.
ASSEMBLE THE SALAD:
Cut the lettuce into 4-6 wedges, depending on how large you like each serving.
Place each wedge on individual plates. Generously drizzle with dressing. Sprinkle chopped bacon, onion, tomatoes, cheese and parsley over top.
Notes
Dressing for Wedge Salad: I've included a recipe for homemade buttermilk ranch dressing, which is a nice creamy, bright contrast to the crisp lettuce. If you prefer, you can take a shortcut and purchase your favorite store-bought Ranch dressing (we like Hidden Valley brand, too) or you can use a blue cheese dressing or a Thousand Island dressing instead. There are no rules!
Lettuce for Wedge Salad:Iceberg lettuce is traditionally used in a Wedge Salad recipe; however, you can substitute with Romaine lettuce if you prefer. To do so, just cut Romaine hearts in half lengthwise to serve.
You can put just about any toppings that you prefer on your Wedge Salad recipe. I've included a few traditional options here (such as blue cheese, bacon, red onion and tomatoes), but you can omit any of those ingredients that you don't like -- or add others such as croutons, chopped fresh herbs, or chopped hardboiled egg. Make it your own!
Don't like blue cheese? Use crumbled feta cheese or grated cheddar cheese instead.
