Preheat your pellet grill to 200°F (93°C) and fill the hopper with charcoal pellets. Make sure you have the flat top installed and the air crisp basket inside it.
Toss the sliced peppers, onion, and garlic with olive oil, salt, pepper, and seasoning mix. Add the Veggies to the Air Crisp Basket leaving room on the side for the sausages.
Prepare the sausages by inserting a probe into one to monitor their internal temperature. Place them on the smoker, leaving space between each link.
Smoke eveything for 1-2 hours or until the sausage is reading about 130°F (54°C).
Take everything out of the air crisp basket and set it aside. Take the probe out of the sausage. Turn the grill off and then turn it aback on and set it to Grill HI. Let it preheat for about 10 minutes. Add the veggies and 1 tablespoon of butter and toss and cooke for 5 minutes or so. Remove the veggies and put the sausages on turning them to give them a nicely browned exterior. This should only take a few minutes. Make sure the sausages read 165°F (74°C), you can check this with an instant read thermometer.
Once the sausage are done split the buns and toast them on the grill, using the sausage juices for added flavor.
Assemble the sandwich with a layer of veggies, a sausage, and any desired condiments or hot sauce.
Enjoy the smoky perfection of this Woodfire Sausage and Peppers Sandwich!
