Heat the oven to 400F. Line a baking sheet with a nonstick silicone baking sheet or spray with nonstick spray.
Trim the top portion of the butternut that can be spiralized, reserving the bottom for another recipe.
Spiralize using the thickest noodle setting of your spiralizer. Transfer to the prepared baking sheet and season with Sweet Heat Dry Rub. Transfer to the oven and roast until tender, about 10 minutes.
Remove from the oven and add enough BBQ Sauce to coat.
Spoon a portion of the coated squash onto a bun. Top with a spoonful of cole slaw and more sauce. Serve immediately.
