Put all ingredients in a food processor and pulse until blended. You can check consistency. If you like it chunky, stop here. If you like a more finely chopped (more like a pesto), then continue pulsing until you get the right consistency.
I like to let it rest for about 15 minutes, then taste and adjust seasonings.
