Remove your steaks from the fridge 10 minutes before cooking. Preheat the grill in two zones: 1 high heat and 1 medium/low heat.
While preheating, make the chimichurri sauce. Pulse all the ingredients together in a large food processor until smooth with some chunks in it, like a thick salsa.
Salt and oil your steaks on both sides, then slide them on to the high heat side of the grill. Cook for 3 minutes on each side to give the steak some color.
Move to the low heat side of the grill to finish cooking. About 2 minutes.
When the instant-read thermometer reads about 110. Remove from grill and loosely tent with foil for 5 minutes.
Slice against the grain and top with chunky chimichurri. Enjoy!
