Creating these amazing fajitas is as easy as following these simple steps:

1. Preheat the Oven: Set your oven to 400°F (200°C) to ensure it is hot and ready for roasting.
2. Prepare Ingredients: Slice the chicken breasts, bell peppers, and red onion into thin strips.
3. Mix Seasonings: In a large bowl, combine olive oil, chili powder, cumin, garlic powder, smoked paprika, salt, and pepper.
4. Combine: Add the sliced chicken and veggies to the bowl, tossing everything to coat evenly with the seasoning mixture.
5. Arrange on Sheet Pan: Spread the seasoned chicken and vegetables in a single layer on a large baking sheet.
6. Bake: Place the sheet pan in the oven and bake for 20 minutes or until the chicken is cooked through and the vegetables are tender.
7. Finishing Touch: After baking, squeeze fresh lime juice over the top for an extra burst of flavor.
8. Warm Tortillas: While the fajitas are baking, wrap tortillas in foil and warm them in the oven for the last 5 minutes of cooking.
9. Serve: Remove the sheet pan from the oven and serve the dish immediately with tortillas and desired toppings.

This straightforward approach guarantees delicious and vibrant fajitas every time!
