Argentines and Uruguayans usually use chimichurri as an accompaniment for grilled meat. While steak is probably the most popular pairing with the sauce, I also love it with any other meat from the grill like pork, chicken, lamb, and fish. You can also use it to dress up your favorite veggies, swipe in on your sandwiches and wraps, or stir it into cooked rice or grains for a zesty and easy side.
