Add even more flavour to your perfectly cooked beef fillet with this delicious chimichurri sauce. Accompanied by tasty grilled vegetables, it makes a perfect mid-week meal for the whole family.
1.Combine beef in a dish with red wine, onion, garlic and oil, and turn several times. Marinate at room temperature for up to 3 hours.
2.Heat barbecue to moderately high. Cook meat until browned on all sides, but still rare inside, turning from time to time, about 20-25 minutes. (To test, pierce with a metal skewer and immediately touch skewer to your lip. If skewer is warm, meat is cooked.)
3.Meanwhile, make chimichurri: combine parsley and garlic in a processor and pulse until finely chopped. Add remaining ingredients and whiz a further 5 seconds to mix. Check seasoning, adding more vinegar, salt or chilli to taste.
4.Remove meat to a warm platter and tent loosely with foil. Stand at least 10 minutes, then slice and serve with chimichurri.
Chimichurri is best served within 2 hours of making.
