When you are ready to grill, preheat grill to medium-high and then season each side of the chicken breasts with The Spice House's Gateway to The North Seasoning

If you are using the iGrill mini thermometer, you can set it up to alert you to turn the chicken. Also, set it up to reach an internal temp of 165 degrees.
Once you turn the chicken, baste it with the Cherry Bourbon BBQ Sauce. Flip once more and baste again. Remove to platter to let rest a couple of minutes.
