Preheat a pan with 1/4 cup oil over medium-high heat. Cut tortillas into thin strips and fry them in batches in the hot oil until crisp. Remove from the pan and allow them to drain on a paper towel. Repeat with remaining tortilla strips, adding more oil as needed then set aside.

Preheat a pot with oil over medium-high heat. Add chopped onion, garlic and chopped jalapeño and sauté until veggies soften.

Add whole chicken breasts, corn, beans, chilli powder, cumin, crushed tomatoes, salt, ¼ cup of cilantro and chicken broth. Bring to a boil and let simmer for at least 25 minutes.

Remove chicken from the pot and shred it using 2 forks. Add shredded chicken back to the soup and simmer another 5 minutes then add lime juice.

Serve the soup with some tortilla strips, pieces of avocado, fresh cilantro and lime wedges.
