A type of basic bread that is flavored with chopped tomatoes. American versions are often given added flavor with tomato juice, which gives the bread an orange or reddish color and a rich tomato taste. Some versions contain a variety of herbs, which provide an additional savory taste. The dough is most often prepared from bread flour or whole-wheat flour or a combination of both and is commonly shaped into rounds and baked as a hearth bread. Other versions have a definite Mediterranean flavor with the addition of chopped sun-dried tomatoes or bits of roasted tomato.
