Chimichurri is one of the most delicious and versatile sauces around. It's traditionally served with grilled steak and is an essential part of an argentinian parrillada or barbecued mixed grill. It goes great with chicken and fish, and is a must with grilled chorizo sausages. Chimichurri works well as a marinade and also gives a spark of flavor to vegetables. Some people prefer more garlic, some prefer only parsley, and others even add fresh tomatoesexperiment to come up with your own signature chimichurri and change the proportions to suit your taste.
