In a large bowl, combine diced chicken breasts with olive oil, taco seasoning, and fresh lime juice. Mix well to ensure the chicken is evenly coated. Let marinate in the refrigerator for at least 30 minutes.

While the chicken is marinating, wash and cut bell peppers into bite-sized pieces. Place the chopped vegetables in a bowl and set aside.

Retrieve the marinated chicken from the refrigerator. Carefully slide the marinated chicken and bell pepper pieces onto the soaked wooden skewers, alternating between chicken and pepper.

Preheat your grill to medium-high heat, around 375°F to 400°F. This ensures that the skewers will cook evenly and develop a beautiful char.

Once the grill is heated, place the assembled skewers directly over the heat. Grill for approximately 10-12 minutes, turning them halfway through.

After grilling, remove the skewers from the heat and let them cool for a few minutes. Garnish with freshly chopped cilantro and serve.
