Choripan
Another cheap and cheerful street food hit, choripan is usually served as an entree at an asado (barbecue).
But thanks to its hands-on shape, this sausage sandwich (where chorizo or sausage teams up with pan or bread) is an ideal snack for travelers on the go.
You can slather it in chimichurri, a spicy sauce made from oregano, parsley, garlic, chili flakes and red wine vinegar -- or salsa criolla, a tomato, onion and red bell pepper variant.
While chorizo is usually made from pork, boar sausages can also be found in some restaurants.
