Chimichurri is an extremely popular condiment in Argentina, it is served with grilled meats (aldo), poultry, fish and vegetables. I love it with barbecued steak and rotisserie chicken. I is also used as a marinade. The ingredients and texture vary from a smooth sauce to a more salsa like texture. The main ingredients are vinegar, oil, garlic and herbs. Below I have a chilli version but it is just as tasty without, experiment until you find a chimichurri that suits your taste.
