Chicken and Chorizo Arepas with Chimichurri

Reina pepiada, a rich combination of chicken, avocado and mayonnaise, is a popular Venezuelan filling for hearty, patty-shaped arepas. The filling combinations are endless, however, so have fun experimenting with your favorite meats and cheeses. If you can't find Harina P.A.N., the popular Venezuelan brand of cornmeal for arepas, use any brand of precooked cornmeal, but be sure to start with only 1 cup water for each 1 cup corn flour, as grinds can vary slightly.
