Preheat your oven to 200°C (400°F).
Season the salmon fillet with salt and pepper.
Place the salmon on a baking sheet lined with parchment paper.
Bake the salmon for about 10 minutes, or until cooked through.
While the salmon is baking, wash and dry the mixed greens.
In a large bowl, combine the mixed greens, julienned carrot, and sliced red onion.
Add cherry tomatoes to the bowl.
In a small bowl, whisk together olive oil and lemon juice.
Drizzle the dressing over the salad and toss gently.
Once the salmon is cooked, flake it into large pieces and add to the salad.
