Substitute flank steak with rump, sirloin or skirt steak
Method
Make the avocado chimichurri sauce by adding all the sauce ingredients except the spring onions and blend in a food processor/blender until almost smooth (try to keep a bit of texture).
Stir in the sliced spring onions and adjust the seasoning to taste. Refrigerate until needed.
Drizzle olive oil onto the flank steaks and generously season with salt and freshly ground black pepper.
Grill the steaks on a hot fire or griddle pan, turning to cook on both sides to your preferred doneness (see cooking guideline above).
Allow the meat to rest for half its cooking time before slicing it into slivers.
Top the caramelised flank steaks with the creamy avocado chimichurri sauce and serve with sides such as crispy roast potatoes and a crunchy salad.
