It should be spelled Chimichurri not Chimichurrie. By the way, if you're still curious the translation for cilantro is coriander. Chimichurri has vinegar it it. There should be about the same amout of vinegar as there is oil.
Some people use a bit more oil than vinegar.
It shouldn't be a paste. The parsley should be chopped into tiny bits with a knife, not mashed into paste with a food processor. Better yet, forget about this recepie and search for the Chimichurri Sauce one on this same page, that is the real thing - for even better results try Griseldas comments.
