While chef Martha Stewart is capable of making difficult dishes like beef Wellington and pasta carbonara, she’s also known for the way she elevates the simple dishes like tuna salad. Tuna salad combines mayonnaise and tuna and can include other ingredients for flavor and texture, but Stewart uses a rather unusual addition: fruit.

In Stewart’s tuna salad recipe, she adds peeled and diced Gala or McIntosh apples, which gives the dish an element of crunch and freshness. You only need one apple for the recipe, plus light mayonnaise, chopped basil leaves, lemon juice, salt, pepper, and, of course, some canned tuna (Stewart prefers water or oil-packed Italian tuna).

Green apples are also good for tuna salad recipes, known for their acidic and refreshing qualities that give sweet and sour notes to the mixture. You can also leave the peels on while you dice the apples for a little boost of nutritional and texture, since apple skins contain plenty of vitamins and fiber.
