Season the shrimp with salt and black pepper.
Heat a skillet over medium-high heat with 1 tablespoon of olive oil and cook the shrimp for 2–3 minutes per side until pink and fully cooked.
Hard-boil the eggs, cool them, peel, and slice into halves or quarters.
Arrange the mixed salad greens on a serving plate or bowl.
Add the cooked shrimp, avocado, sliced eggs, and cherry tomatoes over the greens.
Whisk together the remaining olive oil and fresh lemon juice, then drizzle the dressing over the salad.
Serve immediately, garnished with freshly ground black pepper or chopped parsley if desired.
