Sauté the aromatics.
Heat olive oil in a large pot over medium heat. Add onion and cook for 3–4 minutes until softened. Stir in garlic and cook for 30 seconds.
Add the spices.
Sprinkle in cumin, smoked paprika, and chili powder. Stir for 30 seconds to toast them gently. This builds deep flavor.
Add liquids and vegetables.
Pour in diced tomatoes and chicken broth. Add corn and black beans. Bring to a gentle boil.
Simmer.
Reduce heat and simmer uncovered for 15–20 minutes. Do not overboil, or the broth may reduce too much.
Add chicken.
Stir in shredded chicken and simmer for another 5 minutes. Let it rest for 5 minutes before serving to deepen flavor.
Prepare tortilla strips.
Toss tortilla strips with olive oil. Bake at 190°C (375°F) for 8–10 minutes until golden and crisp. Watch closely, as they brown quickly.
Finish and serve.
Stir in fresh lime juice. Taste and adjust seasoning. Ladle into bowls and top with crispy tortilla
