1 teaspoon pure chile powder
1 teaspoon kosher salt
1/2 teaspoon ground cumin
1/2 teaspoon onion powder
1/4 teaspoon garlic powder
1 tablespoon cornstarch
1/4 cup water
3 tablespoons extra-virgin olive oil
1 whole skinless, boneless chicken breast (about 1 pound), cut into 1/2-inch strips
1 green bell pepper—cored, seeded and cut into thin strips
1 medium onion, thinly sliced
2 tablespoons fresh lime juice, plus lime wedges for serving
8 flour tortillas, warmed in the microwave
Shredded lettuce, shredded cheddar cheese, salsa and sour cream, for serving
In a resealable plastic bag, combine the chile powder with the salt, cumin, onion powder, garlic powder, cornstarch, water and 2 tablespoons of the oil. Add the chicken, bell pepper and onion, seal and knead gently to coat. Refrigerate for 15 minutes.
Heat the remaining 1 tablespoon of oil in a large nonstick skillet until shimmering. Empty the contents of the bag into the skillet and cook over high heat, stirring occasionally, until the vegetables are crisp-tender and the chicken is cooked through, about 6 minutes. Remove from the heat and stir in the lime juice.
Transfer the chicken and vegetables to a large bowl and serve with the warmed tortillas, lettuce, cheese, salsa, sour cream and lime wedges.
