Feel-good factors: Sardines abound in omega-3 fatty acids. Also, because they’re little, they don’t accumulate mercury the way that larger fish can.
Ways to try them: Marinate in olive oil with chiles and herbs, then grill. Marinate as above but skip the chiles; then lay over sliced tomatoes on baguette slices, drizzle with marinade, and broil. Dip in beaten egg, then in seasoned panko (crunchy Japanese-style bread crumbs) and bake.
