Preparation: Set the smoker to 250 degrees using a fruit wood (we like apple or cherry). Coat the pork tenderloin with 2 tablespoons of the Dijon mustard (just to coat and allow the dry rub to adhere). Sprinkle the dry rub liberally around the entire pork tenderloin.
Smoked Pork Tenderloin: Place tenderloin on the smoker for about 45 minutes or until the internal temperature is 125 - 140 degrees Fahrenheit for medium rare, and then remove from heat.
Rest and Slice: Let rest for 20 minutes on a cutting board to allow for carry-over cooking and then slice thin for sandwiches.
Build Pork Tenderloin Sandwiches
Slice the baguette in half lengthwise (horizontally). Layer the bread with some Dijon mustard, a few slices of smoked pork tenderloin, and then top with some crunchy greens and any additional toppings you wish.
For ease of transportation, wrap your sandwiches with kitchen twine so they don’t fall apart.
Notes
When smoking consider using a leave-in thermometer that will monitor both the smoker's temperature and the internal temperature of the tenderloin so it does not overcook. We like the Thermoworks Smoke Unit.
