Lime Pepper Salmon

1 tablespoon olive oil
4 (6-ounce) salmon fillets
4 tablespoons freshly squeezed lime juice
Salt and freshly ground black pepper to taste
Heavy-duty aluminum foil

Cut two 12-inch square sheets of aluminum foil. Grease the shiny side of the foil with the olive oil. Place two fillets side by side on each square, and fold up the outer edges. Drizzle one tablespoon lime juice over each fillet. Season with salt and pepper. Fold and pinch the aluminum foil tightly to create a watertight seal around each pair of fillets. Make sure the packets are airtight by pressing down gently with your hand. If air escapes easily, rewrap. Bake foil-wrapped packets in a preheated 400 F oven for 12 minutes.
