Set your instant pot to saute. Add olive oil or bacon grease and heat. Add diced onions and saute until translucent.
Once the onions have sauteed, add the beans, broth, water, taco seasoning, salt and one of the sliced jalapenos. Place the lid on the instant pot, lock lid; close pressure-release valve. Set instant pot to beans or manual mode and select 1 hour 10 minutes.
When finished, allow for the pressure to release naturally.
Once pressure has released, open the instant pot and transfer to a serving bowl. Garnish with fresh jalapeno slices and cilantro if desired.
