Chimichurri Chicken is chicken that is marinated in homemade Chimichurri Sauce then grilled (or sauteed) and topped with more of that vibrant fresh Argentinian Chimichurri. Chimichurri sauce is not only an amazing topping for Steak, Grilled Pork, and protein, but it’s an incredible marinade. It is vibrant, healthy, packed with flavor, and doesn’t require lengthy marinating for tender, tasty chicken.
