Creating One-Pan Chicken Fajitas is straightforward when you follow these easy steps:

1. Preheat the Pan: Heat a large skillet or frying pan over medium-high heat.
2. Season the Chicken: In a bowl, combine the sliced chicken with olive oil, chili powder, cumin, garlic powder, onion powder, paprika, salt, and pepper. Toss until the chicken is well-coated.
3. Cook the Chicken: Add the seasoned chicken to the hot pan. Cook for about 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
4. Add the Vegetables: Once the chicken is cooked, add the sliced bell peppers and onion to the pan. Stir to combine.
5. Continue Cooking: Sauté the chicken and vegetables together for an additional 5-7 minutes, or until the vegetables are tender but still crisp.
6. Add Lime Juice: Squeeze the juice of one lime over the fajita mixture, stirring to incorporate the flavor.
7. Garnish: Remove from heat and garnish with fresh cilantro if desired.
8. Serve: Serve immediately with warm tortillas.
