My food is a taco it comes from Mexico.I chose this because it’s one of my favorite Mexican foods. You can put a lot of topping on your taco.The word taco is the Mexican equivalent of the word sandwich. National Taco day is on Tuesday, October 4th. The first type of taco was taco de minero. People believe that the word taco originally referred to pieces of paper that miners would wrap around gunpowder and use in holes that were carved into the face of the rock.
