The pan bagnat is essentially a Niçoise salad in sandwich form. For this version, tuna is pureed with red wine vinegar, olive oil, anchovies, and garlic to form a unique sandwich spread inspired by tonnato sauce. Spreading a tangy tuna dressing on the cut sides of the ciabatta allows it to get absorbed into the bread, giving the sandwich plenty of flavor while making it easier to eat.
