Add garlic: Stir in the minced garlic or garlic powder, cooking for an additional 30 seconds until aromatic.
Combine broth and spices: Pour in the chicken broth, diced green chilies, ground cumin, cayenne pepper, paprika, oregano, and lime juice. Season with salt and freshly ground black pepper to taste.
Prepare the beans: Drain and rinse the great northern beans in a strainer. Measure out one big ladleful of beans and add them to a food processor with a splash of broth from the soup. Puree until completely smooth.
Simmer the soup: Add the pureed beans, remaining whole beans, and corn to the soup pot. Bring the mixture to a gentle simmer.
Cook to perfection: Cook uncovered for 15-30 minutes, stirring occasionally, letting the flavors meld and the soup thicken naturally.
Final touch: Remove the pot from heat and stir in sour cream (or Greek yogurt) and shredded cooked chicken until well combined and heated through.
Serve & garnish: Serve immediately in bowls garnished with fresh cilantro, shredded cheese, avocado slices, and tortilla chips as desired.
