Whirl all of that together until it makes a paste. Now take some cut up pieces of chicken (I cut chicken breast halves in half again to make nice pick-up-able quarters) and tuck some of the chimichurri under the skin and spread the rest over the top. Pop it all in a hot oven for 30 minutes until everything is nice and cooked and crispy.
This is delicious hot, but it also makes a fabulous cold picnic chicken. Go chimichurri your chicken!
