Tuna fish sandwich


A tuna fish sandwich, also known as a tuna sandwich, is a sandwich made from canned tuna—usually made into a tuna salad by adding mayonnaise, and sometimes other ingredients such as celery or onion—as well as other common fruits and vegetables used to flavor sandwiches. Common variations include the tuna boat and the tuna melt. The more general term of tuna sandwich may also refer to cuisine utilizing filet of raw or cooked tuna, rather than canned tuna.
In the United States, 52% of canned tuna is used for sandwiches. The tuna fish sandwich has been called "the mainstay of almost everyone's American childhood," and "the staple of the snatched office lunch for a generation."

Ingredients

A tuna fish sandwich is usually made with canned tuna mixed with mayonnaise and other additions, such as chopped celery, pickles or pickle relish, hard-boiled eggs, onion, cucumber, sweetcorn, and/or black olives. Other recipes may use olive oil, Miracle Whip, salad cream, mustard, or yogurt, instead of or in addition to mayonnaise. The sandwich may be topped with lettuce, tomato, cucumbers, bean sprouts, or avocado in any combination.
