Pat salmon filets dry and lay flat, skin side down, in a shallow glass dish.
Whisk together olive oil, lime juice, ginger, vinegar, and sea salt in a small glass bowl.
Pour marinade evenly over the salmon filets. Allow salmon to marinade for 25-30 minutes.
Meanwhile, preheat broiler to 425 degrees F. Arrange an oven rack 6-8 inches away from the oven broiler element.
Transfer salmon to an oven-safe rimmed baking sheet. Broil for 5-7 minutes, depending on the thickness of the salmon filet, until the salmon is cooked through for well-done salmon or until the center is a medium pink for medium-done salmon.
Serve atop arugula with the Watermelon Mint Salsa (below).
