An Argentine condiment used to accompany grilled steak and other meats, chimichurri is a pesto-like sauce made from onions, garlic, parsley, dried oregano, salt, cayenne pepper, oil and vinegar. It is best made fresh, but it is also occasionally available in dehydrated and bottled versions. 

Legend has it that chimichurri was invented by a traveling Brit of some sort, its odd name a bastardization of possible inventors Jimmy McCurry, Jimmy Curry or James C. Hurray. Now a popular accompaniment throughout Latin America, it is often called the ketchup of Argentina.
