Allie Lewis of Everyday Food makes Tortilla Soup.
Preheat oven to 400 degrees. In a large pot, bring chicken, broth, jalapeno, and 8 cups of water to a boil over medium-high heat. Reduce heat to medium; simmer until chicken is cooked through, about 15 minutes. Transfer chicken to a plate; let cool.
Brush both sides of tortillas with oil, stacking them as you go. Cut stack in half, and then slice crosswise into 1/2-inch strips. Place strips on a rimmed baking sheet; bake, tossing strips occasionally, until golden, 15 to 20 minutes.
Using a large spoon, skim fat from surface of broth in pot, and strain liquid through a sieve into a clean pot (you should have about 8 cups). Shred chicken with a fork or with your fingers, and return it to the pot. Stir in 1 teaspoon salt. Divide soup among serving bowls, and add tortilla strips. Garnish as desired.
