In a small bowl, combine the cream cheese, Traeger Pork & Poultry Rub, and the sour cream and mix well. Transfer the mixture to a sturdy, resealable plastic bag and trim 1/2-inch off one of the lower corners with scissors.
Start with a jalapeño slice, add a dollop of the cheese mixture, and if you're including meat, a bite-sized slice. Wrap the stack with a slice of bacon and secure with a toothpick.
When ready to cook, set the Traeger temperature to 350˚F and preheat with the lid closed for 15 minutes.
Place the poppers directly on the grill, close the lid and smoke the peppers for 15-20 or until the meat is cooked.
Remove the poppers from the grill and serve warm. Enjoy!
