Pull the meat from ½ a rotisserie chicken and shred it into smaller pieces. You'll need 2 cups, can add more or reserve for another meal.
Cook:
In a large pot over medium heat, heat oil. Add the onion, garlic, and green chilies and the liquid, and cook, stirring, until the onions are soft and translucent, about 3 minutes. Add the cumin, oregano, and cayenne (if using) and stir for a minute to toast the spices.
Add the white beans, cooked rotisserie chicken, chicken stock, and water into the pot. Stir the soup and bring it to a boil. Reduce the heat and simmer for 15 minutes, covered.
Serve:
Add the juice of 1 lime and chopped cilantro into the pot and stir to combine.
Ladle the soup into bowls and top with avocado slices and a wedge of lime. I love this chili with tortilla chips on the side.
