Hazen is the author of two other appealing cookbooks, Glories of the Vegetarian Table ( LJ 2/15/89) and The Sophisticated Sandwich ( LJ 6/15/89). Here she indulges her fascination with ``filled foods'' to come up with a variety of ethnic appetizers from Caribbean Sweet Potato Balls to Italian Chicken Coppa Rolls. Hazen is knowledgeable and creative, but some of her choices are available in other sources. Though there are color illustrations, the book seems limited, with barely six dozen recipes. An optional purchase.
