Lemon-Caper Tuna Sandwich
"Bread doesn't like the fridge, because it'll totally dry out in there. Don't refrigerate!"—Joanne Chang, Flour Bakery + Cafe, Boston Get the recipe Lemon-Caper Tuna Sandwich ». Joseph De Leo

This briny, tangy sandwich, from Joanne Chang of Flour Bakery + Café in Boston, benefits from sitting awhile after assembly. The oils from the tapenade will seep into the bread, making it moist but not soggy, and the sharp flavors of pickled fennel, capers, and olives will mellow pleasantly.
