Add the drained and rinsed corn, black beans, and shredded chicken. Stir in the tomato sauce, tomato paste, diced tomatoes, and chicken broth. Add the salt, garlic powder, chili powder, paprika, cumin, and fresh-squeezed lime juice. Bring to a boil, then lower the heat and simmer until ready to serve. The longer the soup simmers the more flavorful it will be. Stir in the tortilla strips once you're ready to serve.
