Preheat your smoker to 250 degrees.*once your smoker has reached 250 degrees F. add your favorite wood chips to the smoker tube. We used hickory wood chips for this recipe. While the smoker is heating, remove the sausage from the refrigerator giving it time to come to room temperature.
Rinse the peppers with cold water, and pat dry with paper towels. *I like to use a variety of colors for a more colorful and vibrant dish. But you can use any color peppers you like. Cut the peppers in half, then remove the stem and seeds. Slice the peppers into strips about ½ inch wide.
Remove the outer layer of the onion, then cut it in half and slice it into pencil width slices.
Place the cut peppers and onions into a foil pan that will go into the smoker.
Add the olive oil, kosher salt, black pepper, and garlic powder to the pan and mix to combine.
Cover the pan with aluminum foil.
Place your sausage links in a separate foil pan and lightly coat them with olive oil. Leave this pan uncovered.*Cooking them separately for the first hour allows the sausage to get more of the smoke flavor. The peppers will have a lighter smoke flavor making for a nice contrast. Place the uncovered sausage pan, and the covered peppers mixture in the smoker and cook for one hour.
Remove the aluminum foil from the peppers and onion mixture, then stir to mix them.
Place the sausage links on top of the pepper and onions.
Return the pan to the smoker uncovered and cook for an additional hour, or until the sausage has reached an internal temperature of 165 degrees F.*For a smokier flavor, add more wood chips to the smoker tube. Remove the sausage, peppers, and onions from the foil pan using a slotted spoon or tongs so any extra juices will not carry over to the serving dish.
Serve as is, or on a hoagie roll. The sausage can be sliced or left whole.
