Place everything in a blender and pulse until smooth and the herbs are broken down (but do not liquify the herbs, just break down the herbs until they're small green flecks in the dressing).
Taste and add more seasonings according to preference.
Pour the dressing in an airtight container and chill in the refrigerator for at least 2 hours before using, preferably overnight.
Will keep in the fridge for up to a week.
