This lunchtime classic is often lackluster and flavorless, so we’ve given it an overhaul here. First, we started out with high-quality ingredients like premium canned tuna; then we added fennel and lemon zest for a nice riff.
What to buy: Premium tuna packed in olive oil is paramount. We like Ortiz Bonito del Norte.
Game plan: You’ll need to make the mayonnaise before you begin.
