 Common raw vegetables (in the culinary sense) used in a salad include cucumbers, peppers, tomatoes, onions, carrots, celery, radishes, mushrooms, avocado, olives, artichoke hearts, heart of palm, watercress, parsley, garden beets, and green beans.Nuts, berries, seeds, and flowers are less common components.Hard-boiled eggs, bacon, shrimp, and cheeses may be used as garnishes, but large amounts of animal-based foods would be more likely in a dinner salad.
