¼ cup (2 fl oz) fresh lemon juice or red wine vinegar
2 tbsp fresh lime juice
Instructions
1To make the chimichurri sauce, put all the ingredients in the blender and the secure lid. CHOP for 15-20 seconds, scraping down the side halfway through with a spatula, until well combined.
2Transfer to a bowl. Season with salt and pepper. Press a piece of plastic wrap onto the surface and refrigerate until needed.
3Put the steaks on a plate. Season with salt and pepper. Spoon 2 tablespoons of chimichurri sauce over each steak and turn to coat.
4Preheat a grill pan over medium-high until hot. Drizzle a little oil over the steaks. Cook for 3-4 minutes on each side, or until cooked to your liking. Transfer to a warm platter, cover loosely with foil and set aside to rest for 5 minutes.
5Serve the steaks with the remaining chimichurri sauce.
