Make the mango avocado salsa. Add the diced mango, avocado, cilantro, red onion, and jalapeño to a bowl. Add honey, lime juice, lime zest, and salt. Gently toss to combine. Taste and adjust the seasoning.
Cook the rice. Prepare the rice according to the package directions.
Preheat the oven. Heat the oven to 475°F. Line a baking sheet with foil for easy cleanup.
Season the salmon. In a small bowl, mix the brown sugar, smoked paprika, onion powder, garlic powder, chili powder, kosher salt, and olive oil to form a thick paste.
Prepare the salmon. Place the salmon skin-side down on the lined baking sheet. Rub the seasoning paste evenly over the top of the salmon.
Bake. Roast for approximately 6–12 minutes, depending on the thickness of the salmon and your preferred doneness. For food safety, cook salmon to an internal temperature of 145°F.
Assemble the bowls. Divide the cooked rice between bowls. Flake the salmon into large pieces and place it over the rice. Spoon the mango avocado salsa on top and finish with an extra squeeze of fresh lime if desired.
