The Cobb salad is a main-dish American garden salad typically made with chopped salad greens (iceberg lettuce, watercress, endives and romaine lettuce), tomato, crisp bacon, boiled, grilled or roasted (but not fried) chicken breast, hard-boiled eggs, avocado, chives, Roquefort cheese, and red-wine vinaigrette.
Various stories exist recounting how the salad was invented. One says that it came about in the 1937 at the Hollywood Brown Derby restaurant, where it became a signature dish. It is named for the restaurant's owner, Robert Howard Cobb. Stories vary whether the salad was invented by Cobb or by his chef, Paul J. Posti. The legend is that Cobb had not eaten until near midnight, and so he mixed together leftovers he found in the kitchen, along with some bacon cooked by the line cook, and tossed it with their French dressing.
Another version of the creation is that Robert Kreis, executive chef at the restaurant, created the salad in 1929 (the year the Brown Derby's Hollywood location opened) and named it in honor of Robert Cobb. The same source confirms that 1937 was the reported date of the version noted above, with Cobb making the salad.
Authentic versions of the Cobb salad are prepared using four varieties of lettuce: iceberg, watercress, endives and romaine.
