Cook the salmon: Heat 1 tablespoon of olive oil in a pan over medium heat. Season the salmon fillets with salt and pepper, then cook for about 4-5 minutes per side until fully cooked. Set aside to cool slightly and flake with a fork.

Prepare the salad: In a large bowl, combine the mixed greens, cucumber, avocado, cherry tomatoes, and red onion.

Make the dressing: In a small bowl, whisk together the remaining olive oil, lemon juice, salt, and pepper.

Assemble the salad: Flake the cooked salmon and add it to the salad. Drizzle the dressing over the salad and gently toss to combine.

Serve: Garnish with fresh dill if desired and enjoy!
