Prepare the smoker and set it to 250° F.
Cut the jalapenos in half and scoop out the seeds and ribs.
In a bowl, mix together the cream cheese, green onions, garlic salt, and cumin. If using shredded cheddar add it to the filling. Stir together well.
If using cheddar matchsticks, place them in the bottom of the pepper.
Stuff each jalapeno with the cream cheese mixture.
Wrap bacon around the peppers tightly so no cheese can escape.
Place the peppers on a piece of butcher paper and place it on the smoker.
Smoke for 90 minutes, or until your preferred crispiness is reached.
