Add everything to a food processor and process until smooth.
Taste to correct seasonings.
Consistency should be looser than pesto. You can add more or less water or olive oil depending on your preference. Feel free to get creative and use any leafy herbs you have on hand. Even arugula adds a nice zing.
To Make Salmon
Rinse salmon and pat dry.
Drizzle with olive oil then sprinkle with sea salt and pepper.
Cook or grill in whatever method appeals to you (see above for my recommendations).
