Anchovy

"I revere anchovies," says chef Seamus Mullen. "They're little fish that have tremendous flavor; they're high in omega-3 fatty acids, so they're great for my joints; and they're low on the food chain, so they're sustainable. That, to me, is a true hero food." Chef Mullen isn't the only fan of these small, silvery fish. Anchovies are a staple ingredient in Mediterranean countries, where they're eaten preserved in salt, oil or—as in the case of Spanish boquerones—vinegar.
