Rinse dried beans and set aside.
Turn Instant Pot to sauté mode for 2 minutes.
Add oil to the pot and sauté jalapeños, garlic, and onion for 2 minutes.
Add beans, stock, and green chiles.
Put the lid on and set to pressure cook on high for 50 minutes.
When finished cooking, release the pressure and remove lid.
Using a hand beater, beat the beans until smooth. I like to put a dish towel over the beater and pot since the beans splatter.
Add salt and pepper to taste.
Enjoy hot with cheese on top.
