In a blender, blend together onion, tomatoes, garlic, chipotle chili, jalapeno, salt, and cilantro.
Turn your electric Instant Pot on to Sauté, for 12 minutes, and when it is hot, add the oil.
Once the oil starts shimmering, pour in the blended vegetables and stir well. Keep stirring on and off for 10 minutes until the sauce is relatively thickened.
Add in 4 cups of water, and if you're using the corn tortillas to thicken, add them now.
Add in the soaked beans, set your Instant Pot to manual, High pressure 25 minutes and let it release pressure naturally when finished.
Add in frozen corn and stir to let it heat through, and serve with cheese, slices of avocado, corn tortilla strips or other garnishes.
