Unwrap fish but leave it on the butcher paper. Season with salt and pepper on flesh side only. Sprinkle generously with flour, and then shake off the excess.
In a 12-inch non-stick skillet, heat 2 teaspoons of olive oil over medium high heat until hot but not smoking. Place the fish in the pan skin side down. Cook until golden, about 3 to 4 minutes. Turn the fish over and cook until the flesh is just cooked through and is no longer translucent, about 3 more minutes, depending on the thickness of your fish.
