The European dish that would be impossible to make without goods imported from the Americas during the Columbian Exchange is Tomato sauce and pasta. This is due to the fact that tomato has its prehistoric origin in South America. Eventually, this plant moved to the region of Mesoamerica, between Mexico and Costa Rica and was taken on by the Aztecs. After this, when Spanish colonized this region, they discovered the fruit in the 16th century and took its seeds to Europe.
