Spathcock the chicken so it will fit flat in a Ziplock-style bag.
Add the sugar, honey, salt, pepper, and liquid smoke to the bag and mix well.
Cook sous vide for 4 hours at 150 °F.
Remove bag from water and allow them to cool a bit.
Cover both sides of the chicken generously with the rub of you choice. I used Zavala Barbecue’s Bird Rub.
Preheat the Ninja Foodi Grill to 325 °F; however, you can also do this in the oven under the broiler.
Place the chicken onto the grill for about 15-20 minutes, meat side down and skin side up to allow the skin of the chicken to dry while the meat side browns.
‘Nuff said! Remove the Smokeless Smoked Chicken from the grill, allow to cool some, and enjoy!
