Creating Chicken Tortilla Soup is a straightforward process if you follow these easy steps:

1. Cook the Chicken: In a large pot, heat olive oil over medium heat. Add the chicken breasts and cook until browned, about 6-7 minutes per side. Remove and set aside.
2. Sauté Vegetables: In the same pot, add chopped onion and bell pepper. Sauté for 3-4 minutes until softened. Add minced garlic and cook for another minute until fragrant.
3. Add Tomatoes: Stir in the can of diced tomatoes with green chilies, scraping any bits from the bottom of the pot.
4. Pour in Broth: Add the chicken broth and bring the mixture to a boil.
5. Season the Soup: Stir in the black beans, corn, chili powder, cumin, salt, and pepper. Return to a simmer.
6. Shred the Chicken: While the soup simmers, shred the cooked chicken using two forks. Return the shredded chicken to the pot.
7. Simmer: Allow the soup to simmer for 15-20 minutes, letting the flavors meld together.
8. Prepare Tortilla Strips: If making homemade tortilla strips, cut tortillas into thin strips and fry in oil until golden and crispy. Drain on paper towels.
9. Taste and Adjust: Taste the soup and adjust the seasoning if necessary.
10. Serve: Ladle the soup into bowls and top with crispy tortilla strips and your choice of optional toppings.
