Most salads are served cold, although some, such as south German potato salad, are served warm. Some consider the warmth of a dish a factor that excludes it from the salad category calling the warm mixture a casserole, a sandwich topping or more specifically, name it for the ingredients which comprise it. Leafy vegetable salads are generally served with a dressing, as well as various garnishes such as nuts or croutons, and sometimes with meat, fish, pasta, cheese, eggs, or whole grains.
