Instructions
The sauce couldn't be easier if you use a food processor: Using the pulse function, chop the herbs and garlic all together. Then add the other ingredients and process until you have a smooth (but not entirely uniform) paste. If too thick, add more olive oil. Taste and adjust as you like by adding a bit more spice or vinegar or whatever.
Using a more traditional method: Chop all the solid ingredients finely and put them into a jar, together with the rest of the ingredients, and shake well.
Let the sauce rest for an hour or two before using. (Some recipes call for letting the sauce rest overnight.)
Notes
Quick to prepare, but best if left to rest overnight.
