If you've never tried chimichurri, it's an Argentinean condiment that's sort of like a dressing, but that is typically used as a sauce or marinade. The basic components are parsley, garlic, vinegar, oil, and chiles of some sort, although I've seen dozens of versions. Chimichurri is sometimes referred to as "gaucho," which is also the term for a South American cowboy.
Chimichurri is designed to complement beef because, well, Argentineans like their beef. They eat more of it than anyone else in the world. The Pampas, which are low-lying grasslands, are excellent grazing lands for beef cattle.
I included that last part just to prove that I was listening in my eleventh-grade history and geography class. Thank you.
