Set the Instant Pot on Saute while you prep all the ingredients so it starts to warm up.
Once everything is prepped, first pour in the diced tomatoes, water, and olive oil. Then add the rest of the ingredients to the pot and stir really well.
Once it's stirred well, put the top on the pot, and spin to lock it in. Then make sure the valve on top is set to "sealing".
Set the manual or pressure cook timer to 15 minutes.
Once the timer reaches zero, quick release the pressure.
