Brush the grill gate with some olive oil.
Place chicken breasts on the hot side of the grill.
Let the chicken grill, undisturbed, until the pieces start getting some grill marks.
Then turn the browned chicken over, and move them to the cooler side of the grill.
Cover, and let them finish cooking.
Once the internal temperature of the chicken reaches 160°F remove chicken from the grill.
Please Note: USDA recommended guidelines for cooking chicken to 165°F or until no longer pink in the middle.
I prefer to remove the chicken from the grill when it reaches 160°F, cover it with foil, and let it rest and finish cooking.
The chicken should reach 165°F as it rests; check with an instant read thermometer before serving.
Let it rest 5 to 10 minutes before cutting and serving.
