Preheat oven to 425F. Line a baking sheet with aluminum foil, spray with non-stick cooking spray, and set aside.
To prepare the mango avocado salsa, combine the diced mango, avocado, bell pepper, red onion, lime juice, salt and cilantro. Stir to combine. Place in the refrigerator until ready to use.
In a small bowl, whisk together the honey, chili powder, lime juice, oil, cilantro and salt until combined.
Place salmon, skin side down, on the baking sheet covered with aluminum foil. Spoon or brush the honey glaze on top of the salmon.
Bake at 425F for 10-12 minutes, until salmon is cooked through and easily flaked with a fork.
Top with mango avocado salsa and serve.
