Preheat the oven to 400 degrees F. Line a baking sheet with foil and place the salmon filet onto the foil. Set aside.
In a small bowl, whisk together the salmon marinade ingredients until well combined. Pour the marinade over the salmon.
Bake for 12-15 minutes, or until the salmon is opaque and flakes easily. Remove from the oven and allow to cool for 5 minutes.
While the salmon cooks, add the salad dressing ingredients to a small mixing bowl. Whisk to combine. Set aside.
To a serving bowl, add the spring mix. Top with the cucumber tomatoes, avocado, red onion, olive, and cheese.
Add the salmon to the salad (whole filet or large pieces), and top with as much dressing as you like. Serve immediately.
Notes
You can use skin-off or skin-on salmon for this salad. If using skin-on, be sure to use your spatula to separate the meat from the skin once the salmon is done baking. You should be able to slide it between the two parts of the fish and have them come apart easily.
