Grill fish in foil packets. Fold four 24x18-inch pieces of heavy foil in half to make 18x12-inch rectangles. Place a fish fillet in center of each foil rectangle. Season with salt and pepper. Drizzle olive oil over fish. Bring up opposite edges of oil and seal with a double fold. Fold remaining edges together to completely enclose fish, leaving space for steam to build. Grill as above.
