I also mashed half an avocado with the remaining chimichurri, wich gave the sauce a really nice creamy texture. (isachandra.com)
In a small food processor, blender or using an emulsion blender, combine the ingredients until a nice creamy texture is achieved, adding a little more olive oil if need be. (beyondthepeel.net)
This looks delicious and I bet the squash adds an nice creamy texture.... (browneyedbaker.com)
