Preheat oven to 400 degrees F.
Brush fillets on both sides with oil and season with salt and pepper. Heat a large, oven-safe nonstick saute pan over high heat, add the fish, and cook until golden brown, about 2 minutes. Brush with some of the glaze, turn over, and continue cooking (on the stovetop or in the oven) for 3 to 4 minutes or until just cooked through. Brush with more of the glaze and remove from the heat.
Ladle some of the broth into large shallow bowls, place fish in the middle, glazed side up, and sprinkle some of the couscous around the fish
. Serve immediately.
