Rich, delicious sardines not only contain more of the good stuff (omega-3s, calcium) and less of the bad ( mercury
) but are a sustainable choice—i.e., these little guys are not on the verge of extinction. Mashed with canola mayonnaise in a sardine salad, they are the foundation of a formidable tower of nutrients, including sliced avocado, hard-boiled egg, tomato, and arugula.

, pair the fish with ripe tomato and savoy cabbage or Swiss chard. Note:
Cornichons are small, sour pickles.
