Preheat oven to 450°F. Combine sour cream and soup mix in a bowl. Combine next 4 ingredients in a shallow dish. Dip fish into sour cream mixture, then lightly coat with breadcrumb mixture. Arrange fish in a lightly oiled baking dish. Drizzle oil over top. Bake about 8 minutes, until fish is lightly browned. Turn and bake another 5 minutes or until golden.
