To a large bowl add the capers, lemon juice and Dijon mustard. Whisk together. While whisking, drizzle in the olive oil in a steady stream. Whisk in 1/4 teaspoon salt. To the dressing add the beans and mash gently with a spoon. Add the tuna, flaking it with a fork into bite sized pieces as you add it to the bowl. Toss lightly to coat. Add the endive, treviso, arugula, shaved fennel, parsley leaves and the remaining 1/2 teaspoon salt on top of the tuna mixture. Using your hands, toss the salad together bringing the dressing up from the bottom of the bowl until everything is coated evenly.
