1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil.

2. Place the salmon fillet on the prepared baking sheet, skin side down. Sprinkle salt evenly over the salmon. Bake for 12 to 15 minutes, or until the salmon is cooked through and easily flakes with a fork. The internal temperature should reach 145°F (63°C) for safe consumption.

3. While the salmon is baking, prepare the mango salsa. In a medium bowl, combine the diced mango, avocado, red chili pepper, and scallions. Mix well until all ingredients are evenly distributed. Set aside.

4. When the salmon is done, remove it from the oven and let it rest for a few minutes. This allows the juices to redistribute, resulting in a more tender and flavorful fish.

5. To make the lime sauce, whisk together 3 tablespoons of freshly squeezed lime juice with 2 tablespoons of sweet chili sauce in a small bowl. Taste and adjust the sauce as needed, adding more lime juice for tanginess or sweet chili sauce for sweetness.

6. Serve the baked salmon hot, topped with a generous spoonful of mango salsa and a drizzle of the tangy lime sauce on the side. Garnish with fresh cilantro or flat-leaf parsley for a burst of freshness. Enjoy this tropical-inspired dish with your favorite sides for a complete and satisfying meal.
