This Argentinean staple is a flavor-packed condiment that elevates any cut of beef. Or really, any grilled anything.
Unlike most chimichurri recipes, mine minimizes the amount of oil involved. I believe the oil should be potent and flavorful, but you shouldn't use any more than is necessary to provide a conveyance method for the other flavors (particularly the garlic and red pepper).
While you could certainly attempt this without a food processor, you should be prepared for a lot of tedious mincing in order to achieve the desired outcome. You'll likely be rewarded with an ugly green stain on your cutting board for all your extra effort!
In a food processor, combine parsley, cilantro, shallot, and garlic, and pulse until finely minced.
Transfer to a small bowl, and add good olive oil, lime juice, kosher salt, and crushed red pepper. Mix thoroughly.
Serve at room temperature.
