In a dutch oven or large saucepan, heat the olive oil over medium heat. Add in the onion and jalapeño and sauté for 8-10 minutes, or until the onions are translucent. Add in the garlic and cumin and sauté for 1 minute. Add in the tapioca flour, potatoes, and vegetable broth, stirring as you pour the broth in. Add in the white beans, corn, salsa verde, green chiles, salt, pepper and oregano. Let the soup come to a boil, and then turn it down and let simmer for 30 minutes, to let the potatoes cook. Stir frequently. Once the potatoes are cooked through, serve with cilantro, tortilla chips, lime wedges, and/or avocado! Store leftovers in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to a year.
