Grilled Vegetables with Herb Vinaigrette
Small eggplants, often labeled "Italian" or "Asian," have fewer seeds than large eggplants and are good for grilling. We used small purple Italian eggplants and graffiti eggplants, named for their eye-catching purple-and-white striped skin. We used two kinds of radicchio: Verona, which has darker-than-usual garnet leaves, and Treviso, which has long, slender leaves. Grilling mellows radicchio's bitterness.
