Avocados are a native fruit of the Americas with their likely origin being Central Mexico.[1] The trees and fruit have been cultivated by pre-Columbian civilizations from South Central Mexico for nearly 9,000 years.[2][3] As such, sliced or mashed avocado has been eaten on some sort of bread, flatbread, or tortilla (often heated or toasted) since humans first started consuming avocados, and before any documented or written history.
