Whisk together the brown sugar and all spices for the salmon in a small dish.
In another dish, whisk together the orange juice, olive oil and lime juice along with 2 teaspoons of the spice blend.
Pour on top of the salmon and marinate for at least 30 minutes.
Meanwhile, dice the mangoes and peppers and add to a bowl with the onion, cilantro and lime juice. Set aside.
When the salmon is done marinating, sprinkle on top the rest of the spice blend and pat into the skin.
Heat 1 tablespoon of oil in a non-stick skillet. Once warm, add the salmon, skin side up and cook for 4-6 minutes, then flip and cook an additional 4-6 minutes or until cooked through the center.
It should easily flake off the skin when it is done. You can flip it back to be face down to get it nice and crispy and blackened if desired.
Serve with jasmine rice, mango salsa and a fresh squeeze of lime juice. Also delicious with my chipotle aioli or other spicy sauce.
Notes
I recommend yellow mangoes for this recipe, but you can sub for the red variety if that's all you have access to.
