This is part of an Argentinean Asado. This juicy steak is probably one of the most popular parrilla items requested throughout Argentina. So why is it called chorizo? It's not a sausage, but is a NY Strip (among other names) and I guess you could say it is sort of sausage shaped. It is certainly not round. Can be served with chimichurri (try recipe #381098, my favorite) and a simple salad of lettuce, tomato, onion, with a light vinaigrette dressing.
