SAUTE: Heat the oil in a 4 quart (or larger) dutch oven or soup pot (or on the saute setting in your instant pot) over medium-high heat. When warm, add the onions, peppers, garlic, and bay leaves and saute for 5-6 minute or until the veggie soften.
STOVE TOP: Add the black beans, 6 cups of stock, oregano, and cumin and bring to a boil, then reduce the heat too low, cover, and simmer for 1 ½ -2 hours or until the beans are cooked through and the liquid has thickened to your liking. You can also puree ½ the soup in the blender if you want it to be thicker. Season with red wine vinegar, sugar, and 1 teaspoon of salt. Stir and adjust with additional salt as needed. Allow the soup to cool for 15 minutes. IT should thicken a bit as it sits. Top with chopped avocados, and serve with cooked rice!
INSTANT POT: Add the black beans, 5 cups of stock, oregano, and cumin. Cover, make sure the vent is sealed. Cook on manual high pressure for 30 minutes. If using organic or older beans, they may require additional time. Once the time goes off, allow a natural pressure release for 10 minutes. Then do a quick release to let out any remaining pressure. Stir the soup and test the beans for doneness; remove the bay leaves. You can puree 1/2 the soup in the blender if you want it to be thicker. I usually just smash using a wooden spoon on the walls of the pot until it reaches my desired consistency. Season with red wine vinegar, sugar, and 1 teaspoon of salt. Stir and adjust the salt as desired. Top with chopped avocados, and serve with cooked rice!
