A winter salad is a dish that typically consists of mixed greens, such as lettuce and spinach, along with other vegetables like carrots, celery, and radishes. It may also include fruits like oranges and grapefruit, nuts, seeds, and a dressing made from ingredients like olive oil, vinegar, honey, mustard, or citrus juice. The term "winter salad" is often used to describe this type of dish because it's typically served during the colder months when fresh produce is abundant and hearty greens are in season.
