Arepa
Arepa is a type of flatbread made of ground maize dough stuffed with a filling, eaten in northern parts of South America since pre-Columbian times, and notable primarily in the cuisine of Colombia and Venezuela, but also present in Bolivia, Ecuador, and Central America. Initially, arepa flour was made by grinding maize at home. In the 1950s, precooked arepa flour was invented by Luis Caballero Mejías [es], a Venezuelan engineer, and became an instant success.
