Preheat your gas grill or set your charcoal to heat up. This step is crucial for achieving that lovely grilled flavor.
In a medium bowl, mix together the balsamic vinegar, dijon mustard, brown sugar, salt, garlic, and black pepper until well combined.
Add the chicken thighs into the marinade, ensuring each piece is well-coated. You can also use a gallon-size resealable plastic bag for easier handling.
Let the chicken marinate for at least 30 minutes. If you have time, you can let it sit in the fridge overnight for even more flavor.
When the grill is preheated, place the marinated chicken on it. Grill on medium-low heat for about 8 minutes.
Turn the chicken only once, around the 6-minute mark, to achieve those perfect grill marks.
Once the chicken is cooked through and no longer pink in the center, remove it from the grill and let it rest for about 5 minutes.
Slice the chicken into strips and serve it over fresh greens. You can also add rice or noodles if you’re feeling indulgent.
