Tuna salad (deli)

Creamy and savory, with a mild fishy note and some crunch from added vegetables.

Lens analyzed

Deli tuna salad is canned tuna mixed with mayonnaise and usually celery, onion, or relish, sold pre-made in a deli case for sandwiches or scooping onto greens. Deli versions tend to be creamier and more heavily seasoned than a quick homemade batch.

Where it comes from

Tuna salad became a deli-counter staple in North America as canned tuna turned a coastal food into a pantry item nationwide, and delis began premaking mayonnaise-based salads as a fast lunch option starting in the mid-20th century.

Buying it

Check the sell-by date on the deli container closely, since mayonnaise-based salads spoil faster than most other deli items.

Storing it

Mayonnaise-based salads don't hold up well outside the fridge, so refrigerate it right away and finish it by the date on the container.

Keeps about 3 days in the fridge.
