While Cobb and Chef's salads are similar, they're not the same. The key difference lies in the preparation: a Cobb salad features chopped ingredients, whereas a Chef's salad typically has larger, unchopped pieces. Additionally, Chef's salads often include diced ham or other meats. For dressing, a Cobb salad usually has a tangy vinaigrette, contrasting with the ranch or blue cheese dressing often found on a Chef's salad.
