Begin by cutting the chicken breast into bite-sized pieces, aiming for uniformity to ensure even cooking. In a mixing bowl, combine the chicken with olive oil, minced garlic, dried basil, dried oregano, salt, and pepper. Toss thoroughly to coat the chicken completely in the flavorful marinade. Let it sit for at least 15 minutes to allow the flavors to infuse the meat.

Take soaked wooden skewers or metal skewers and start threading the marinated chicken pieces onto them, leaving a little space between each piece for even cooking. Add mozzarella cubes intermittently to the skewers for a delicious surprise on every bite. Aim for a colorful arrangement by incorporating bell peppers or cherry tomatoes if desired, enhancing both flavor and presentation.

Preheat your grill to medium-high heat, approximately 375°F to 400°F. Place the assembled skewers on the grill, ensuring they aren't overcrowded, which helps with even cooking. Grill the skewers for about 15 minutes, turning them every few minutes. Watch for the chicken to become golden brown and the mozzarella to melt into a delicious gooey texture.

Once the Garlic Mozzarella Chicken Skewers are perfectly grilled, remove them from the heat and let them rest for a couple of minutes. This allows the juices to redistribute. Drizzle with balsamic glaze, if desired, and sprinkle fresh parsley or basil on top for a burst of color before serving. Enjoy these delightful skewers hot off the grill!
