"My inspiration for this splendid recipe came from a dish on the menu at Longhorn® Steakhouse. I've guessed how it's made and decided to add strawberries to the salsa, but I am sure it will be fine with just pineapples. Strawberry preserves serve as the marinade base, mixed with soy, vinegar, and sesame oil."
Mix strawberry preserves, soy sauce, apple cider vinegar, sesame oil, garlic powder, onion powder, ginger, and pepper together in a bowl to make marinade. Pour 1/3 cup into a glass measuring cup; reserve. Place salmon fillets in the bowl.
Marinate salmon in the refrigerator for 1 hour.
Mix strawberries, pineapple, onion, and parsley in a bowl to make salsa. Cover with plastic wrap and refrigerate.
Preheat grill for medium heat and lightly oil the grate. Oil a stainless steel grill basket. Place salmon fillets skin-side up in the basket; cook for 6 minutes. Flip and continue cooking skin-side down, about 6 minutes more.
Divide salmon fillets among serving plates; drizzle reserved 1/3 cup marinade on top. Spoon salsa on top.
