1 pound boneless skinless chicken breasts, thinly sliced
1 red bell pepper, thinly sliced
1 green bell pepper, thinly sliced
1 yellow bell pepper, thinly sliced
1 large yellow onion, thinly sliced
2 tablespoons olive oil
1 tablespoon chili powder
1 teaspoon ground cumin
1 teaspoon smoked paprika
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon crushed red pepper flakes
1/2 teaspoon salt
1/4 teaspoon black pepper
8 small flour tortillas
Optional toppings: sour cream, shredded cheddar cheese, chopped cilantro, lime wedges
Preheat the oven to 400°F (200°C).
In a large bowl, combine the chili powder, ground cumin, smoked paprika, garlic powder, onion powder, crushed red pepper flakes, salt, and black pepper.
Add the sliced chicken breasts to the bowl and drizzle with 1 tablespoon of olive oil. Toss to coat the chicken evenly with the spice mixture.
Add the sliced red, green, and yellow bell peppers and sliced onion to the bowl. Drizzle with the remaining 1 tablespoon of olive oil and toss everything together until well combined.
Spread the chicken and vegetable mixture evenly on a large rimmed sheet pan in a single layer.
Bake in the preheated oven for 20 to 25 minutes, stirring halfway through, until the chicken is cooked through and the vegetables are tender and slightly charred.
Remove the sheet pan from the oven and let it rest for 5 minutes.
Warm the flour tortillas in the oven for 2 to 3 minutes or microwave them for 20 seconds.
Serve the chicken and vegetables on warm tortillas with your choice of optional toppings such as sour cream, shredded cheddar cheese, chopped cilantro, and lime wedges.
