This was part of our delish Menu #66257
I did place both on the grill at the same time. Seared the steak four minutes per side. Removed and tented over foil while the onions continued the cook. To the chimichurri sauce I added fresh oregano and used champagne vinegar. Salt was just a pinch. Loved the garlic. I did place all the sauce ingredients into the processor to blend to a nice sauce for ease instead of waiting to remove then whisk in the oil and vinegar. Made for ZWT 2011 Thanks bunches.
