Oysters take very little time to cook. Our pan-broiled hors d'oeuvre, which consists of oysters tossed with herbs and showered with olive oil and Parmesan, spends just minutes in the oven; serve with crusty bread for soaking up the sauce.
Preheat broiler. Stir herbs, red-pepper flakes, oil, and vinegar in a large bowl. Add oysters, and toss to coat.
Transfer oyster mixture to a shallow baking dish. Sprinkle Parmesan over oysters, and season with pepper. Drizzle with oil. Broil until golden brown and bubbling, about 2 minutes. Serve.
