Tuna salad

Tuna salad is a salad dish consisting of tuna and mayonnaise. The tuna used is usually pre-cooked, canned, and packaged in water or oil. Pickles, celery, relish, and onion are popular ingredients to add. Tuna salad is regularly served by itself, or on top of crackers, lettuce, tomato, or avocado; it can also be used to make tuna fish sandwiches. In Belgium, the dish pêches au thon/perziken met tonijn is made from halved canned or fresh peaches stuffed with tuna salad. It is widespread throughout the country, and, due to its ease of preparation, it is common fare at potlucks. In the United States, tuna salad is often considered its own dish. However, it may be added to noodles with its standard ingredients (onions, mayonnaise, and celery) to make a tuna pasta salad. Tuna salad is also commonly seen in American salad bars.[citation needed]
