In Mexico, the word taco is a generic term like the English word sandwich. A taco is simply a tortilla wrapped around a filling. Like a sandwich, the filling can be made with almost anything and prepared in many different ways (anything that can be rolled inside a tortilla becomes a taco). The contents of a taco can vary according to the geographical region you are eating them. The taco can be eaten as an entree or snack. They are made with soft corn or fried corn tortillas folded over.
