Instructions
Place potatoes in a large saucepan and pour in enough water to cover them by 2 inches. Set pan over high heat and bring water to a boil; reduce heat to medium and simmer for 6 minutes.
Add green beans and cook until potatoes are fork-tender and green beans are crisp-tender, about 1 to 2 minutes more; drain and transfer all vegetables to a large bowl.
Meanwhile, in a small bowl, whisk together broth, thyme, basil, oregano, vinegar, mustard, and oil; season to taste with salt and pepper.
Add half of the dressing to potatoes and green beans; toss to coat.
Place 2 lettuce leaves on each of the 4 plates. Top each with 1/4 of potato-green bean mixture, 1 1/2 ounces of tuna, 1/2 tablespoon of capers, 1/2 an egg, 1/4 of the red onion, 1/4 of the tomato, and 4 olive halves.
