In a small mixing bowl, combine Butter, Mayo, Parmesan, Garlic, Oregano, Lemon Juice, Basil & Salt and stir well.
Lay Salmon skin filet side down on sheet of aluminum foil and spoon sauce over Salmon, then loosely close up foil.
Cook for approx. 10 minutes on Grill at 400 degrees {no need to flip}. Salmon will be done when meat flakes easily. Easy peasy, and no mess or lingering odors. Just incredible salmon deliciousness!
