Basically, the choripán is a dish that is basically a grilled chorizo sausage, sliced in two lenghtwise is served between two pieces of toasted baguette bread; it is prepared usually with French type bread. The popularity of this simple dish with Argentinians puts it among the ten favorite dishes of Argentina.
The choripán has all three characteristics of casual dining: easy to make, quick to eat and relatively inexpensive. The three basic ingredients are the bread, sausage and the condiments (or absence of) that accompany it. The chorizo is a key player in the Argentinian Asados (barbecue events) and often they are served as a first course to the meal. The sausage is roasted on the barbecue, it is then eaten like a sandwich (sánguche de chorizo as it is referred to sometimes). It is prepared by the sausage cooked in the oven or on the grill until its color turns dark red, the typical barbecued sausage color, then the bread is sliced in two and toasted on the same grill, then the choripán is put together with the chorizo sliced in two lenghtwise (what they call mariposa cut - butterfly cut) and some chimichurri spread over it.
