A type of Italian yeasted flat bread made with white flour that is similar to a crispy pizza crust. It has a delicious peppery flavor and a crunchy, cracker-like texture. Some versions contain bits of prosciutto ham and grated hard cheeses, such as parmesan, that are kneaded into the dough before baking. The dough is formed into round or rectangular shapes. Pizza rustico is often served with antipasto courses or as an accompaniment to a meal.
