Lean tri-tip steaks marinated in the classic chimichurri marinade cooked on a barbecue or under a grill. The marinade is a mixture of red wine vinegar, garlic, shallot, fresh coriander, parsley, oregano leaves, oil and seasoning.
Remove the steaks from the fridge at least 1 hour before cooking to bring up to room temperature.
To prepare the marinade; in a large bowl mix all the ingredients together. Pour half the marinade into a shallow non-metallic dish and reserve the remainder. Place the steaks in the marinade mixture and coat well on both sides. Cover and refrigerate for 2 hours, or if time allows overnight.
Remove from the marinade (discard the marinade) and cook under a preheated moderate grill or on a prepared barbecue according to your preference (based on a 5cm thick steak): Rare -2 minutes on each side, Medium Rare - 3-4 minutes on each side, Medium - 5-7 minutes on each side.
Remove the steaks from the pan, transfer to a warm plate, cover with foil and rest for a few minutes.
Slice the steaks, spoon over the remaining marinade and serve with roasted vegetables.
