Preheat oven to 400°.
Line a rimmed baking pan with foil.
Place salmon on foil, skin side down.
In a small bowl, combine olive oil and seasonings; drizzle over salmon.
Bake at 400° for 20 minutes or until the internal temperature reaches 145°F and fish flakes easily with a fork.
While salmon is baking, prepare salsa by combining all ingredients in a separate bowl.
