Season the salmon with cumin, achiote, salt and pepper.
In a large sautué pan over medium-high heat, warm the oil. Place the salmon in the pan. Sear until golden brown underneath, about 4 minutes. Turn the salmon over and continue cooking until golden underneath, about 4 minutes or until done. Transfer the salmon to plate, cover with aluminum foil and set aside.
Meanwhile make the sauce: In a saucepan, place the oil, tomatoes, red bell pepper, onions, scallions, garlic, achiote, cumin, salt and pepper. Cook for 6 to 8 minutes, stirring occasionally.
To serve: Place the cooked salmon on a plate and drizzle with the creole sauce.
