1. 6 tablespoons cooking oil
2. 8 (6 inch) corn tortillas, halved and cut crosswise into 1/4-inch strips
3. 1 onion, chopped
4. 4 large cloves garlic, smashed
5. 1 tablespoon paprika
6. 2 teaspoons ground cumin
7. 1 teaspoon ground coriander
8. 1 teaspoon chili powder
9. 1/4 teaspoon cayenne
10. 1 1/2 quarts canned low-sodium chicken broth or homemade stock
11. 3 cups canned crushed tomatoes in thick puree
12. 2 bay leaves
13. 2 1/2 teaspoons salt
14. 1/4 cup lightly-packed cilantro leaves
15. 3 tablespoons chopped cilantro (optional)
16. 1 3/4 pounds boneless, skinless chicken breasts, cut into 3/4-inch pieces
17. 1 avocado, cut into 1/2-inch dice
18. 1/4 pound Cheddar, grated
19. Lime wedges, for serving
- In a large heavy pot, heat the oil over moderately high heat. Add half the tortilla strips and cook, stirring, until pale golden, about 1 minute. Remove with a slotted spoon and drain on paper towels. Repeat with the remaining tortilla strips.
- Reduce the heat to moderately low. Add the onion, garlic, and spices; cook, stirring, for 5 minutes. Add the broth, tomatoes, bay leaves, salt, cilantro leaves, if using, and one-third of the tortilla strips. Bring to a simmer. Cook, uncovered, for 30 minutes; remove the bay leaves.
- In a blender, puree the soup in batches; pour it back into the pot. Add the chicken, bring the soup back to a simmer, and cook until just done, about 1 minute. Stir in the avocado.
- To serve, put the remaining tortilla strips in bowls, top with the cheese, and pour in the soup. Sprinkle with the chopped cilantro, if using, and serve with the lime wedges.
