Creating these delicious Sheet Pan Chicken Fajitas is as easy as following these steps:

1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C).
2. Prepare the Chicken and Vegetables: In a large bowl, combine the sliced chicken, bell peppers, and onion.
3. Add Olive Oil and Spices: Drizzle the olive oil over the mixture and sprinkle the chili powder, cumin, paprika, garlic powder, salt, and black pepper. Toss everything together until well coated.
4. Spread on Sheet Pan: Spread the chicken and vegetable mixture evenly on a large sheet pan. Make sure the pieces are not crowded, allowing them to roast properly.
5. Bake: Place the sheet pan in the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender.
6. Add Lime Juice: Once cooked, remove the pan from the oven and squeeze fresh lime juice over the top for added flavor.
7. Garnish: If desired, sprinkle fresh cilantro over the fajitas before serving.
8. Serve: Transfer the fajitas to a serving platter or serve directly from the sheet pan.

These simple steps will guide you to a flavorful meal that everyone will love.
