Pre-heat grill to a 500F degrees by turning all burners on high.
Cover the entire chicken with a generous layer of olive oil. Be sure to get all sides covered. Season with salt, pepper and red chili pepper flakes. Chicken must be at room temperature before grilling.
Place chicken on grill, right in the center. At this point turn the middle/ center burner completely off and turn the left and right side burners down, enough to bring the grill temperature down to about 350F degrees. This is the set temperature to grill the perfect chicken, evenly!
Let chicken cook for 15 minutes then flip sides and cook for 15 more minutes.
Meanwhile, in a small glass combine the softened cubes of Dorot ginger, honey and juice from one lemon. Mix with a fork to combine.
Flip the chicken to the other side and allow to cook for 15 minutes on this side as well. It’s important that the chicken get some grill time on both sides before starting to glaze it with the honey ginger sauce because the honey will brown the chicken quickly giving the false impression that the chicken is thoroughly cooked.
After both sides have cooked for 15 minutes, continue to flip the chicken every 15 minutes, now brushing with a coat of ginger honey sauce between each time you flip the chicken. Each side should be turned about 3 times, one being only seasoned with oil, salt and pepper and other two flips, brushed with sauce. The total cook time is up to 1 1/2 hours, depending on grill temperature, size of chicken and cooking preference.
Just prior to chicken being done, add lemon slices to the grill, cut side down.
Remove chicken from grill and serve with grilled lemon slices.
