Originating in Argentina and Uruguay, chimichurri is an uncooked condiment that is typically served brushed, basted, or spooned onto food (most often meat like chicken and steak) as it cooks.
If you have a food processor: Add everything to your food processor except the olive oil. Process until finely minced. Do not over mince.
Transfer to a bowl and add the extra virgin olive oil. Combine and, if time allows, let it sit for at least 15 minutes before seasoning with salt.
Best served at room temperature.
If you don't own a food processor: Simply chop all the the ingredients up very finely and combine with extra virgin olive oil.
