Mushrooms a la Grecque

GREEK-STYLE marinated vegetables are served as a first course in France, but can be easily added to a summer buffet. Some chefs prepare the mushrooms with tomatoes; others do not include them. I enjoy them both ways, and use tomatoes in the summer or whenever I find them red, ripe, and full flavored.

Although mushrooms are my favorite, pearl onions are also excellent prepared in a similar fashion.
