01 - In a medium bowl, whisk together the balsamic vinegar, olive oil, honey, garlic, rosemary, oregano, salt, and black pepper until well combined.
02 - Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring all pieces are evenly coated. Seal and refrigerate for 1 to 4 hours.
03 - Preheat an outdoor grill or grill pan over medium-high heat. Remove the chicken from the marinade, allowing any excess to drip off.
04 - Grill the chicken for 6 to 8 minutes per side, or until the internal temperature reaches 165°F and the juices run clear.
05 - Transfer the grilled chicken to a plate, tent loosely with aluminum foil, and let rest for 5 minutes before slicing.
06 - Garnish with fresh parsley and serve with lemon wedges alongside roasted vegetables, grilled asparagus, or a fresh green salad.
