What staple product of Italian cuisine came from Latin America?

The staple product of Italian cuisine that came from Latin America is the tomato.

While tomatoes are now considered an essential ingredient in many Italian dishes, they were not originally part of the Italian diet. They were introduced to Europe by Christopher Columbus in the 16th century after he brought them back from his travels to the Americas.

It took some time for tomatoes to become popular in Italy, as they were initially thought to be poisonous. However, they eventually gained acceptance and became a vital part of Italian cuisine.
