Creating a delicious Salmon Nicoise is simple if you follow these steps:

1. Cook the Green Beans: Bring a pot of salted water to a boil. Add the green beans and blanch for about 3-4 minutes until tender-crisp. Drain and run under cold water to stop the cooking process.
2. Prepare the Salmon: Season the salmon fillets with salt and pepper. Heat a tablespoon of olive oil in a skillet over medium-high heat. Add the salmon, skin side down, and cook for about 4-5 minutes. Flip and cook for another 3-4 minutes until cooked through. Remove from heat and let rest.
3. Prepare the Vinaigrette: In a small bowl, whisk together the remaining olive oil, Dijon mustard, red wine vinegar, salt, and pepper until well combined.
4. Assemble the Salad: On a large platter or individual plates, arrange the mixed greens. Top with the quartered potatoes, green beans, halved cherry tomatoes, olives, and hard-boiled eggs.
5. Add the Salmon: Flake the cooked salmon into large pieces and place on top of the salad.
6. Drizzle with Vinaigrette: Pour the prepared vinaigrette over the salad, ensuring an even distribution.
7. Garnish: Finish with fresh herbs for an aromatic touch.

By following these steps, you will have a stunning Salmon Nicoise ready to serve.
