Prepare mashed potatoes and stuffing (let cool slightly).
1 cup mashed potatoes, 1 cup prepared stuffing
Preheat smoker to 225°F (maple, hickory, or apple).
On a sheet of foil, create a bacon weave (7 strips one direction, 6 the other).
13 strips bacon
Mix half the poultry seasoning into the ground turkey. Put turkey into a zip-top freezer bag, seal, and flatten evenly.
1 tbsp poultry seasoning, 1 lb ground turkey
Slice the bag open (down the middle of the top, then across the bottom) to create a flat turkey rectangle.
Use the bag to roll turkey into a log; seal/pinch ends.
Add fillings near one end (leave space on edges): mashed potatoes → stuffing → cranberry sauce.
3/4 cup cranberry sauce
Transfer to bacon weave and roll up using the foil. Set seam-side down.
Sprinkle with remaining poultry seasoning.
Smoke until internal temp reaches 145°F.
Make cranberry BBQ sauce: combine sauce ingredients in a pot, bring to a boil, reduce heat, and simmer 15 minutes, stirring often.
1 cup cranberry sauce, 2 tbsp cider vinegar, 1/4 cup brown sugar, 2 tbsp molasses, 1 tbsp Worcestershire sauce, 1 tsp garlic powder, 1 tsp onion powder
Brush fatty with cranberry BBQ sauce at 145°F and continue cooking until 165°F internal.
Rest 10 minutes, slice, and serve.
