Combine extra virgin olive oil, garlic, and rosemary in a small bowl. Extract juice from lemon into marinade adding lemon rind to mixture once completed.
Divide marinade evenly into 2 zip lock bags.
Place 2 pieces of chicken into each zip lock bag and marinate in the refrigerator for at least 6 hours or overnight.
Prepare an outdoor grill for grilling. Place the chicken skin side down over medium-low heat for approximately 25-30 minutes, or until skin begins to peel.
Turn chicken and cook for an additional 10 minutes until done.
Remove from grill. Let chicken cool to room temperature and chill in refrigerator.
