Creating Grilled Honey Mustard Chicken is straightforward if you follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together honey, Dijon mustard, olive oil, apple cider vinegar, garlic powder, onion powder, salt, and pepper.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring it is well-coated. Seal the bag or cover the dish, and refrigerate for at least 30 minutes, or up to 2 hours for maximum flavor.
3. Preheat the Grill: Heat your grill to medium-high heat, about 375°F to 400°F (190°C to 200°C).
4. Remove Chicken from Marinade: Take the chicken out of the marinade, letting any excess drip off. Discard the marinade.
5. Grill the Chicken: Place the chicken on the grill. Cook for 5-7 minutes on one side, then flip and grill for another 5-7 minutes, or until the internal temperature reaches 165°F (75°C).
6. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for 5 minutes. This helps retain the juices.
7. Garnish and Serve: Optionally, garnish with fresh parsley before slicing and serving.

These steps will guide you in preparing this incredible dish with ease.
