Place all ingredients into a small blender or food processor, juicing and zesting the lime (you'll only need about ½ tsp of lime zest) directly into the food processor. Process until the sauce becomes thick and even in color. Scrape the sides of the food processor with a rubber spatula if needed and continue to blend until everything is well incorporated. Serve immediately or store in an airtight container in the fridge for 2-3 weeks.
