Creating Chicken Fajitas is an easy process if you follow these simple steps:

1. Marinate Chicken: In a bowl, combine olive oil, chili powder, cumin, smoked paprika, salt, and pepper. Cut the chicken into strips and toss with the marinade. Allow it to marinate for at least 20 minutes.
2. Preheat Skillet: Heat a large skillet or frying pan over medium-high heat until hot.
3. Cook Chicken: Add the marinated chicken in a single layer. Cook for about 5-7 minutes, or until fully cooked. Ensure no pink remains.
4. Add Vegetables: Once the chicken is cooked, add sliced bell pepper and onion to the skillet. Stir-fry for an additional 5 minutes until vegetables are tender yet crisp.
5. Finish with Lime: Squeeze the juice of one lime over the mixture. Stir to combine and heat for another minute.
6. Warm Tortillas: In a separate skillet, lightly warm the tortillas for about 20-30 seconds on each side or until flexible.
7. Serve Immediately: Transfer the chicken and vegetable mixture into a serving bowl.
8. Garnish: Sprinkle with fresh cilantro and prepare any optional toppings you would like to serve.
