Preheat your oven to 400ºF. Lightly spread the oil on the bottom of a shallow baking dish and lay the fillets on it. Mix together the wine, pepper, chile powder, and parsley, pour over the fish and bake in a 400º oven for 12 to 15 minutes or until the fish flakes easily when tested with a fork. Carefully lift the fish out of the poaching liquid, place on a platter or serving plates, garnish with parsley and lemon, serve. Serves 4
