Tuna salad is a popular dish made primarily from canned tuna, which is a type of fish. The tuna is usually mixed with ingredients like mayonnaise, celery, onion, and pepper to enhance its flavor and texture. It can be served on its own, in a sandwich, or atop a bed of greens. This dish is not only tasty but also nutritious, as tuna is a good source of protein and omega-3 fatty acids. Tuna salad is often enjoyed as a quick meal or snack, making it a convenient option for busy lifestyles.
