For an extra layer of flavor, consider adding a drizzle of balsamic glaze after broiling. If you don't have fontina cheese, provolone or mozzarella can be substituted. Toast the bread slices lightly before adding pesto to prevent the sandwich from becoming soggy. Feel free to add other vegetables such as roasted red peppers or grilled zucchini.
