Buy a little extra salmon the next time you’re fillet-shopping and cook it all up at once. The next day, pair the cold leftover fish with a hit of lemon-spiked mayo and briny capers for a fancy-looking salmon sandwich that’s perfect lunch for one.
A po’ boy is a New Orleans sandwich traditionally made with deep-fried oysters (another sustainable seafood pick) or shrimp. In N’awlins’ lingo, these po’ boys are served “dressed” with lettuce, tomato and seasoned mayo. Look for U.S. farmed tilapia, as the most sustainable choice; otherwise, substitute domestically raised catfish.
