Use the saute function on your instant pot and add the oil and onion. Stir and saute for 3 minutes, then add the garlic and cook for another minute.
Turn the heat off and add all the other ingredients, except the cilantro, to the pot. Mix to combine well. Secure the lid on your pot and make sure the pressure valve is closed. Cook on high pressure for 15 minutes. Let the pressure release naturally for 5 minutes, then do a quick release. (I usually put a damp towel over the valve to prevent splatters.)
Serve alone, over rice, or with some crusty bread and garnish with cilantro.
Enjoy!
