Season salmon fillets on both sides with salt and black pepper.
Heat 1 tablespoon of olive oil in a non-stick skillet over medium-high heat.
Place salmon in the skillet skin-side up and sear for 4 to 5 minutes per side until the internal temperature reaches 145 degrees Fahrenheit.
Remove salmon from the skillet and allow it to rest for 3 minutes, then flake into large bite-sized pieces.
In a small mixing bowl, whisk together extra virgin olive oil, lemon juice, Dijon mustard, and honey to create the vinaigrette.
In a large salad bowl, combine mixed baby greens, sliced red onion, and halved cherry tomatoes.
Toss the salad base with half of the prepared vinaigrette.
Arrange the flaked salmon and sliced avocado on top of the greens.
Drizzle the remaining vinaigrette over the salad and serve immediately.
