Sardines are full of rich nutrients and have more than most fish one can consume. Rich in omega-3 fatty acids, vitamin B12 and selenium, and they provide a rare natural source of vitamin D. These sardines are high-quality boneless fish filets bathed in heart-healthy olive oil. These sardines are ready to be eaten straight out of the can, and make a delicious afternoon snack on crackers, or bread with butter or mayo and a squeeze of lemon.
