Tuna salad

Tuna salad starts with a blend of two main ingredients: tuna and mayonnaise. The tuna used is usually pre-cooked, canned, and packaged in water or oil. Pickles, celery, relish, and onion are foremost among the ingredients that are often added. When the mixture is placed on bread, it makes a tuna salad sandwich. Tuna salad is also regularly served by itself, or on top of crackers, lettuce, tomato, or avocado. Chopped boiled eggs may be added. Relish adds a piquant flavor yet, unlike commonly added vegetables, requires no chopping.
