Preheat your Traeger grill to 225* with the super smoke feature on.
Line a cookie sheet with parchment paper.
Remove the Spam from the cans and season all sides generously with Smoke Junkie seasoning.
Drain the juice from the can of pineapple (reserve the juice) and then season the pineapple chunks with Smoke Junkie.
Arrange the pineapple on the cookie sheet along with the seasoned Spam bricks.
Place the cookie sheet in the Traeger grill and smoke for at least one hour.
While the meat and pineapple smokes, make the sauce.
Combine the reserved pineapple juice, teriyaki sauce, Japanese BBQ sauce, BBQ sauce, and hot sauce in a bowl.
Whisk to combine and add the brown sugar.
Once the meat has smoked for at least 60 minutes, remove it from the grill.
Using a large chef's knife, cut the Spam into 1-inch cubes.
Combine the Spam cubes and smoked pineapple in a baking dish and pour the prepared sauce over.
Stir to coat.
Return the baking dish to the grill and increase the heat to 300*.
Continue cooking for at least 30 minutes until the sauce has thickened and the Spam burnt ends are glazed.
Serve the Spam burnt ends with smoked pineapple with toothpicks and enjoy warm.
