Pat salmon dry. On a large baking sheet, lay out an extra long piece of aluminum foil. Drizzle with oil or spray with non-stick cooking oil. Place the salmon in the middle of the foil. Drizzle salmon with olive oil and season with salt and pepper.
Place a second large piece of foil on top and seal as you would a papillote.
Cook for 30-35 minutes in the over.
After salmon has been in for 5 minutes, cook couscous according to package instructions.
Divide couscous between two dishes. Serve salmon over couscous. Sprinkle with lemon pepper seasoning to taste.
