Creating the Salmon Avocado Mixed Greens dish is straightforward if you follow these simple steps:

1. Preheat Your Oven: Preheat your oven to 400°F (200°C) for roasting the salmon.
2. Prepare the Salmon: Season the salmon fillets with salt and pepper. Drizzle with olive oil and lemon juice.
3. Roast the Salmon: Place the seasoned salmon on a lined baking tray. Roast in the preheated oven for 15-20 minutes, or until the salmon flakes easily with a fork.
4. Prepare the Salad: While the salmon is baking, assemble the mixed greens in a large bowl. Add cherry tomatoes, cucumber, and avocado slices.
5. Dress the Salad: Drizzle with a bit of olive oil and lemon juice. Toss gently to combine.
6. Plate the Salad: Once the salmon is done, remove it from the oven and let it cool for a couple of minutes. Place the roasted salmon on top of the mixed greens.
7. Add Optional Toppings: If desired, sprinkle crumbled feta or goat cheese and sesame seeds over the salad for added flavor.
8. Serve: Serve immediately while the salmon is warm over the fresh greens.

Following these steps ensures that you create a vibrant and delicious dish effortlessly.
