The wedge salad is classic Americana diner eats; nowadays, salads like mesclun, or 'spring mix' and spinach have replaced the classic iceberg lettuce, which is now relegated to school lunch salads (always served on pizza day with kernel corn), or as burger lettuce.
Historically, the wedge salad has used a bleu cheese dressing...which, no matter how much I TRY to like, I just CAN'T. Some people will substitute Ranch dressing, but it's easiest to make your own dressing at home. Like with my Caesar salad, instead of using raw eggs & oil and making an emulsion, you can use mayonnaise (which is, coincidentally, an emulsion of eggs and oil) as a shortcut. Crisp bacon, croutons, and tomato wedges complete the salad, proving that, sometimes, less IS more.
