Creating Caprese Balsamic Grilled Chicken is straightforward when you follow these clear steps:

1. Prep Marinade: In a bowl, mix balsamic vinegar, olive oil, minced garlic, salt, and pepper.
2. Marinate Chicken: Place chicken breasts in a resealable plastic bag, pour in the marinade, and seal the bag. Refrigerate for at least 30 minutes to marinate.
3. Preheat Grill: Heat a grill or grill pan over medium-high heat.
4. Grill Chicken: Remove chicken from the marinade and discard the excess. Grill chicken breasts for about 6-7 minutes per side or until they are fully cooked (internal temperature reaches 165°F).
5. Add Toppings: In the last couple of minutes of cooking, place the sliced mozzarella on top of each chicken breast, allowing it to melt slightly.
6. Prepare Tomatoes: While the chicken cooks, toss halved cherry tomatoes with a pinch of salt and some olive oil in a bowl.
7. Remove & Rest: Once cooked, remove the chicken from the grill and let it rest for a few minutes.
8. Serve: Top each chicken breast with fresh basil leaves and a generous spoonful of the seasoned cherry tomatoes.
9. Optional Glaze: Drizzle with additional balsamic vinegar or honey for an extra kick of flavor, if desired.

Following these steps will ensure a juicy, flavorful dish that will have everyone asking for seconds.
