Place all ingredients, except for the additional chopped cilantro, into the Instant Pot. Lock lid into place, ensuring the vent is sealed. Press the "Manual" button followed by the "Adjust" button to set the pressure to high. Set the timer for 40 minutes.
The Instant Pot will preheat and start the time automatically. Once the 40 minutes is up, wait 5 to 10 minutes and manually release any steam and remove the lid. Remove the cilantro stems and ladle into serving bowls. Sprinkle with chopped cilantro if desired. In addition, toppings such as plain Greek yogurt or diced avocado can also be added! Serve and enjoy.
