Sardines are a super seafood: they're virtually mercury-free, high in omega-3s, and are also packed with iron, calcium, magnesium, phosphorus, potassium, zinc, copper, and B vitamins. Instead of a tuna salad sandwich, try this sardine salad sandwich instead. In you aren't a fan of seafood salad sandwiches, eat sardines whole on some toasted bread, mustard, and greens.
