Marinate the Chicken: In a bowl, combine the sliced chicken with chili powder, cumin, paprika, salt, black pepper, and cayenne pepper (if using). Mix well to coat the chicken evenly and let it sit for a few minutes to soak in the flavors.

Heat the Oil: In a large skillet, heat the olive oil over medium-high heat until shimmering, creating the perfect base for cooking.

Cook the Chicken: Add the seasoned chicken to the skillet and cook for about 5–7 minutes, or until it’s cooked through and no longer pink. Remove the chicken from the skillet and set aside.

Sauté the Vegetables: In the same skillet, add the sliced bell pepper and onion. Sauté for about 3–4 minutes, or until the vegetables are tender but still crisp, bringing out their natural sweetness.

Add Garlic: Stir in the minced garlic and cook for an additional 30 seconds until fragrant, filling your kitchen with a delightful aroma.

Combine and Heat: Return the cooked chicken to the skillet with the vegetables. Squeeze lime juice over the mixture and stir to combine. Cook for another 1–2 minutes to heat through, allowing all the flavors to meld beautifully.

Garnish: Remove from heat and garnish with fresh cilantro if desired, adding a pop of color and flavor to your dish.

Serve: Enjoy the chicken fajita mixture in warm tortillas, over rice, or on its own for a satisfying meal.
