Make the salsa: In a medium bowl, combine mango, red bell pepper, red onion, jalapeño, cilantro, lime juice, honey, and salt. Toss gently and chill while you cook the salmon.
Pat the salmon dry. Brush all over with olive oil. In a small dish, mix salt, pepper, chili powder, garlic powder, and lime zest, then rub evenly over the salmon.
Heat a large skillet over medium-high until hot. Place salmon skin-side down and press lightly for 10 seconds to prevent curling.
Sear without moving for 4 to 5 minutes until the skin is crisp and the sides turn opaque about halfway up. Flip and cook 2 to 4 minutes more, until salmon flakes easily or reaches 125 to 130°F for medium.
Transfer to plates and rest 2 minutes.
Top generously with mango salsa and serve immediately.
Notes
For extra heat, keep some jalapeño seeds in the salsa. This recipe also works great on the grill—oil grates well and cook over medium-high direct heat.
