The arepa is a corn-based dish from the northern Andes in South America, now spread to other areas in modern Latin American countries. Colombian and Venezuelan migration to the U.S.A. and elsewhere has made arepas available almost worldwide. It is basically a flat (the flatness varies) cake of cornmeal which is then grilled, baked or fried. It is often split in half and filled with cheese, deli meats, and a great variety of fillings, in which case it is know as arepa rellena.
