Add the cream of chicken soup, water, salsa, chicken, corn, beans, chili powder, cumin, garlic powder, and red pepper flakes to a large slow cooker. Season with salt and pepper, to taste.
Cook on high for 3 to 4 hours.
Remove the chicken from the slow cooker. Shred or chop the chicken into bite-sized pieces. Place the chicken back into the slow cooker and stir.
Thin the soup with extra hot water, if needed.
Serve the soup in individual bowls and top with soft tortillas, tortilla chips, avocados, tomatoes, cheese, cilantro, or sour cream. Enjoy!
