3 ounces of canned tuna has nearly 40% of your daily value
That tuna fish sandwich at lunch never sounded more appealing—just ask for some tomato, lettuce and whole-grain bread, and you’re good to go. Or aim for a heart-healthier version (sans-mayo) and make it at home: mix a can of tuna with 2 teaspoons olive oil, a squirt of fresh lemon juice, and some capers, scallions or red onion. Finish with a touch of salt and pepper for protein-packed perfection.
