Place all ingredients in a blender, except the olive oil, and blend well until you achieve the desired texture.This can be more or less fine depending on your tastes.
Pour into a bowl, add the olive oil and mix.
And There you go ! That's it, nothing could be simpler!
Notes
Above all, do not add salt otherwise your tapenade will be unavoidable because there is enough salt in the olives and anchovies.
