In a food processor, add all ingredient.
Process until pureed, about 20 seconds.
Stop & scrape the sides of the bowl if needed to get everything pureed.
Transfer the salsa verde from the food processor to a small saucepan.
Bring to a simmer over medium-high heat.
Simmer for 5 minutes, stirring frequently, reducing the heat as needed to maintain the simmer.
The mixture should darken in color as it cooks.
Turn off the heat, and let the mixture cool at room temperature, approximately 1 hour.
Transfer to a lidded container and refigerate until ready to serve.
