Boil in salted water until tender, 10–12 minutes. Drain and cool slightly.
Blanch the Green Beans
Boil 3–4 minutes, then shock in ice water to retain color and crispness.
Prepare the Eggs
Whisk olive oil, vinegar, Dijon mustard, garlic, salt, and pepper. Serve in a small bowl on the side.
Arrange the Platter
On a large serving platter, create separate sections for each ingredient: potatoes, green beans, cherry tomatoes, olives, red onion, capers, tuna, eggs, anchovies (if using), and salad greens.
Serving
Let guests assemble their own portions, adding dressing as desired.
Notes
Tip: For visual appeal, alternate colors and textures in each section. Use small bowls for capers, olives, and anchovies to prevent them from mixing with other ingredients.This method turns a classic salad into a fun, interactive, and elegant dining experience, perfect for entertaining.
