Chapati (alternatively Chapatti, Chappati or Chapathi) is an unleavened flatbread (also known as roti) from Bangladesh, India, Nepal, Pakistan, and Sri Lanka. It is a common staple in South Asia as well as amongst South Asian expatriates throughout the world. Versions of the dish are also found in Central Asia and the Horn of Africa, with the laobing flatbread serving as a local variation in China. Chapati is known as sapati or doday in the Pashto language. (source)
