Blackened Mahi mahi with Pineapple Strawberry Jalapeño Salsa

First, prepare the blackened seasoning by combining smoked paprika, garlic powder, onion powder, salt and pepper, marjoram, oregano, and cayenne (if using). For the salsa, dice the strawberries, pineapple, and jalapeño, then squeeze the lime over them and mix. Cover the Mahi-Mahi fillets with softened butter, then generously coat both sides with the blackened seasoning. Place the seasoned fish in a hot pan and cook for just a few minutes on each side until it reaches an internal temperature of 137-140°F. Once cooked, pull the fish off the heat. Serve immediately with the pineapple strawberry jalapeño salsa.
