Beans (think dry beans, not green beans) go to the Americas too. Chiles/peppers/capsicum, eggplant, pumpkins and squash, avocado, peanuts as well.

*Banana probably originates from SE Asia
Wheat to the fertile crescent (West Asia) along with beer and bread. Wine most likely belongs there too.
SEA pride!
