The modern empanada is believed to be a derivative of the Indian samosa. The first empanadas were made in the Iberian peninsula, specifically Portugal and Galicia (the north-westernmost region of Spain), during the Medieval period and at the time of the Moorish invasion. Recipes for empanadas have been found from as early the start of the 16th century.
Since their arrival in Argentina some centuries ago, empanadas have become a fast-food staple in Buenos Aires. They can be easily found in little take-away pizzerías all over the city as well as in many restaurants. A typical Argentine empanada is made with a flour-based dough (rather than maíz, or corn) and some of the most common kinds are: ground beef, cubed beef, chicken, ham and cheese, ham and onion, spinach, and humita (sweet corn with white sauce). The fillings often include other ingredients such as peppers, onions, hard boiled eggs, and olives. Empanadas can be either baked (Salta-style) or fried (Tucuman-style).
