A salad is a dish that's usually cold and often includes lettuce or other greens. However, some salads don't have any greens but instead have lots of mayo — like tuna salad or chicken salad.
While your idea of a salad might be iceberg lettuce, tomatoes, carrots, croutons, and a creamy dressing, salads come in many different forms. You can make a pasta salad or a tuna salad or an egg salad. Other salads are based on big pieces of bread, or meat, or cheese — and still others are dessert salads made with gelatin or whipped cream and fruit. Salad comes from the Latin phrase herba salata, or "salted vegetables."
