Combine: In a small bowl combine all marinade ingredients and whisk to combine. Place the lemon pepper marinade in a 1-gallon plastic baggie and then place the chicken in the bag. Gently combine the marinade with chicken and slowly seal the baggie releasing as much air as possible.
Marinate: Marinate the chicken in the baggie in the refrigerator for at least 2 hours (up to 8).
Prepare Grill: Set up grill for direct grilling targeting 400 degrees in the cooking chamber. Remove the chicken from the marinade and then season it on both sides with the SPG rub. Discard the marinade.
Grill: Grill the chicken over the direct heat for 4 minutes per side or until the chicken as a nice crust on both sides. Then move to indirect until the internal temperature of the chicken reaches 160 degrees Fahrenheit using a good instant read thermometer. Be sure you stay close to grill so you can flip them when you see the right amount of color.
Notes
Ingredients: This recipe works for any chicken cut, from the breast to thighs. If you make this for bone-in chicken breasts (4) then split the two breasts in two baggies. It's very tight to try and fit four bone-in chicken breasts into one gallon size baggie.
