Directions

1. Heat a large skillet over medium-high heat. Add sausage; cook and stir until browned and crumbly, 5 to 7 minutes. Drain and discard grease.
2. Meanwhile, preheat a smoker, according to manufacturer's instructions, until temperature is a steady 220 degrees F (104 degrees F).
3. Remove silver skin and fat from pork loin. Cut pork loin, lengthwise, in center, not cutting all the way through to the other side. Open the 2 sides and spread them out like an open book; season both sides with pork rub.
4. Spread one side pork with cream cheese, then layer jalapeños, pimentos, and browned sausage evenly over top. Carefully roll up pork loin into a fairly tight log; secure with cooking twine.
5. Smoke in the preheated smoker until an instant-read thermometer inserted into center reads 140 to 145 degrees F (60 to 63 degrees C), about 2 hours. Transfer pork loin to a platter; wrap tightly in aluminum foil. Rest before serving, for at least 20 minutes.
