Choripán de Argentina

I went to the Saturday Community Farmers’ Market in Fairfax, VA, at lunchtime today. There's a sandwich stand -- Il Bastone -- that makes choripanes from their own Argentine chorizo and chimichurri. I had a choripân made with piqante (spicy) chorizo. I also took a frozen pack of Chorizo Piqante home for me to cook (and a frozen pack of Bier Rostwurst, a Swiss and Volga German recipe from Argentina’s Calamuchita Valley).
