Creating your Caprese Balsamic Grilled Chicken is a straightforward process. Follow these steps for best results:

1. Marinate the Chicken: In a bowl, mix balsamic vinegar, olive oil, minced garlic, salt, pepper, and Italian seasoning. Place chicken breasts in the mixture and marinate for 20-30 minutes.
2. Preheat the Grill: Heat your grill to medium-high heat.
3. Grill the Chicken: Remove chicken from marinade and discard the leftover marinade. Grill chicken for 6-7 minutes on each side, or until cooked through and juices run clear.
4. Prepare Toppings: While the chicken is grilling, in a bowl, combine halved cherry tomatoes, mozzarella balls, and basil leaves. Toss gently to mix.
5. Serve the Chicken: Once chicken is done, remove from the grill and let it rest for 5 minutes before slicing.
6. Top with Caprese Mixture: Spoon the tomato and mozzarella mixture on top of each chicken breast.
7. Drizzle with Balsamic Reduction: If desired, drizzle extra balsamic glaze over the top before serving.

Following these steps will ensure your Caprese Balsamic Grilled Chicken is bursting with flavor.
