2. For the mayo: Place the garlic and egg yolks into a food processor and process together for 10 seconds. With the machine still running, slowly add the oil in a steady stream until thick and creamy, then add the parsley, dill, mustard, lemon juice, vinegar, capers and anchovies, pulse a few times until the mixture is smooth and refrigerate until needed.

to warm through. Toast the buns. Place some lettuce, a tuna steak, onions and a spoon of mayonnaise on the bun, season and top with the other half, secure with a rosemary sprig if needed, serve three per person.
