Step 1: Put everything in IP, except for the salt and olive oil. Let cook on manual for 25 minutes, release pressure naturally (NPR). When able to open, ladle the onion, peppers out with a spoonful of the beans, and bit of broth then transfer to blender. Blend until smooth. Pour this mixture back into IP, with remaining beans, and stir. Throw away Kombu, Cinnamon stick and bay leaves!
Step 2: Add salt and olive oil and mix well. Put back on pressure for 10 minutes and NPR. Enjoy. Or puree all of it for a more refried beans kind of dish.
