Ingredients
Cod fillets (4 about 6 ounces), white wine (1/4c), extra virgin olive oil (1tbsp), black pepper (1/2tsp), salt (1/2tsp), butter (3tbsp), finely chopped onion (1small), sliced lemon (1).

Method of preparation:-
First heat the grill for medium-high heat. Take a small frying pan, melt butter in it. Add onions in it and cook for about 1 to 2 minutes. Add white wine, reduce the heat and keep it to simmer for more 3 minutes. Now take off the pan from heat and keep it to cool slightly. Apply the olive oil on the fillets and then sprinkle salt and pepper to taste. Now place the fish fillets on the oiled grill rack and cook for 8 minutes. Baste the cod with butter sauce and then turn the sides. Cook for more 6 to 7 minutes or until the fish gets opaque. Baste an additional 2-3 times. Now take out the fish from the grill. Top it with lemon wedges and then serve it.
