Melt the butter in a small heavy saucepan over low heat. Add the olive oil and blend well. Add the bread crumbs, salt, pepper, cayenne, tarragon, oregano, parsley, garlic and green onions and mix well. Remove from the heat. Place the oysters in a 9-inch round gratin dish. Cover the oysters evenly with the bread crumb mixture. Bake at 425 degrees for 20 to 25 minutes or until the edges of the oysters curl and the topping is brown.
Note: May place in individual ramekins and bake for 15 to 20 minutes or until the edges of the oysters curl and the topping is brown.
