Creating the 30 Minute Sheet Pan Chicken Fajitas is as simple as following these steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C) to ensure it’s hot when you add your sheet pan.
2. Prepare the Chicken and Vegetables: In a large bowl, combine the sliced chicken, bell peppers, and onions.
3. Seasoning Mix: In a small bowl, whisk together the olive oil, chili powder, cumin, garlic powder, paprika, salt, and black pepper to create a flavor-packed seasoning mix.
4. Combine: Pour the seasoning mix over the chicken and vegetables, then toss everything to ensure all pieces are evenly coated.
5. Arrange on Sheet Pan: Spread the seasoned chicken and vegetable mixture onto a large, lined baking sheet in a single layer for even cooking.
6. Bake in Oven: Place the sheet pan in the preheated oven and bake for 20 minutes, or until the chicken is cooked through and the vegetables are tender and slightly charred.
7. Warm the Tortillas: While the chicken and vegetables are baking, warm your tortillas in a skillet over medium heat for about 1-2 minutes on each side, or wrap them in foil and place them in the oven for the last 5 minutes of cooking.
8. Remove from Oven: Once cooked, take the sheet pan out of the oven and let it cool for a minute.
9. Serve: Serve warm Chicken Fajitas with tortillas, lime wedges, and fresh cilantro.
