Instructions
- Step 1: Place 10 oz quartered new potatoes in a pot of salted water and bring to a boil. Cook for 12-15 minutes until tender but firm, then drain and set aside.
- Step 2: Bring another pot of salted water to a boil. Add 10 oz trimmed haricots verts and blanch for 2-3 minutes until bright green and crisp-tender. Drain and plunge into ice water to stop cooking.
- Step 3: In a small bowl, whisk together 1/3 cup extra virgin olive oil, 3 tbsp red wine vinegar, 1 tsp Dijon mustard, 1 minced garlic clove, 3 tbsp finely chopped mixed fresh herbs, salt, and freshly ground black pepper until emulsified.
- Step 4: Heat a non-stick skillet over medium-high heat. Season 8 oz fresh tuna steak with salt and pepper. Sear tuna for 2 minutes on each side until a golden crust forms but the center remains rare. Remove and let rest for 3 minutes, then slice into 1/2-inch thick slices.
- Step 5: On a large platter, arrange the cooked potatoes, blanched haricots verts, 3 quartered hard-boiled eggs, 1/2 cup Niçoise olives, 2 tbsp capers, and sliced tuna in separate sections.
- Step 6: Drizzle the herb vinaigrette over the entire salad just before serving to preserve the vibrant colors and fresh flavors.
