Flat Irons are a good one to smoke.
Tried a new on. Took some boneless chicken thighs and cut them into 2" or so squares after removing the excess fat. Seasoned them on both sides with my favorite yard bird rub. Added a touch more brown sugar and let them sit about an hour. Took some thick sliced bacon and cut it into 2" pieces. Alternated chicken and bacon on a skewer. On the smoker at 325 for about 45 minutes. I turned a couple times. The last 15 minutes brushed it with Lane's Vinegar sauce.

Also used the bacon and some andouille sausage disks to make a shot glass of sorts. Filled the cup with mixture of cream cheese, extra sharp cheddar, parmesan cheese, and a little of the lanes. Smoked along with the chicken basting the top as they finished. Served with some sauce for dipping.
A couple new options to try.
