Hedgehog Mushrooms à la Grecque

Mini-mushrooms marinated in a mild court bouillon do not lose their shape or pleasing bounciness. Choose small specimens for the best effect—but larger ones will do if they are trimmed and sliced about ¼ inch thick. Serve this fresh salad-y dish as part of an antipasto mixture, with olives, artichoke hearts, and shrimp. Or toss with poultry or ham dice and serve on greens, as a lunch salad.
