Add all ingredients except olive oil to the blender and course briefly.
Put blender on constant speed and add oil in a thin stream until fully combined.
Put chimichurri in a jar and chill in the fridge... When the olive oil heats up during blending, it will have a much stronger taste than normal. As the oil cools, the flavor will relax and becomes more desirable.
Remove chimichurri from fridge to thaw before using.
