  • Preheat oven to 400°F.
  • Brush both sides of the salmon fillets with 1 tablespoon of the olive oil and place them on a baking sheet, skin side down (if there is skin).
  • Combine the brown sugar, chili powder, ground cumin, red pepper flakes, salt, smoked paprika, and oregano. Mix well.
  • Season the tops of the salmon fillets with half of the spice mixture.
  • Add the peppers, onion, and garlic to a medium bowl and toss with the remaining tablespoon of olive oil and spice mixture.
  • Spread the vegetables around the salmon fillets on the baking sheet.
  • Place the sheet in the preheated oven and bake, tossing halfway through, for 20-25 minutes, or until the salmon flakes away easily with a fork and the vegetables are tender.
  • Garnish with the cilantro and lime slices, if desired.
