Remove the stuff from the cavity of the chicken (what is a giblet anyway?). Wash inside and outside of chicken with running water.
At this point, you have options. You could brine with your favorite brine. Or marinade for a few hours. Or, as in this recipe, I just went safe with a lemon pepper chicken.
Pat dry. Rub inside and out with oil.
Salt and pepper lightly, again inside and out. Sprinkle with oregano and then use the lemon pepper very generously, again inside and out. Cut the lemon in half and put them in the cavity. Bag the chicken and throw it in the refrigerator while you get the grill set up.
Following the grill’s instructions for using the rotisserie. In my case, I remove the grates and attach the rotisserie motor. Heat the grill on high, bringing the temperature to 450 degrees. I added a pan of water to catch the drippings (prevents flair ups) and keep the chicken moist.
Add the chicken to the skewer (pierce the lemon halves if you have to). Tie that bad boy down with a cotton string (don't use nylon, nothing good can come from that). Make sure you tie the wings so they don't dip down into the flames. Tie the legs as well.
Put the chicken on the grill and add the weight. Adjust it until the chicken spins freely and is in balance.
Close the cover and rotate the chicken over indirect medium high heat until the juices run clear and the temperature is 180° in the thickest part of the thigh, about 1 to 1 1/2 hours. Don't peak too often or you'll let the heat out. Check after about 30 minutes to make sure the pan still has water and that the skin isn't browning too fast (if it is, just turn the grill down a bit). Remember, all of this will vary depending on your grill and the size of your bird.
Once done, carefully remove from the grill with big cooking mitts. Let the bird rest for about 10 minutes before carving it up.
