Follow these steps for a seamless cooking experience:

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. In a large skillet, heat the olive oil over medium heat. Add the sliced onions and cook until they become translucent, about 5 minutes.
3. Toss in the garlic and cook for another minute until fragrant. Add the shredded mushrooms to the skillet.
4. Sauté the mushrooms until they are golden brown and tender, roughly 8-10 minutes.
5. Mix in the barbecue sauce, soy sauce, smoked paprika, chili powder, salt, and pepper. Stir well to combine.
6. Transfer the mushroom mixture to the prepared baking sheet and spread it out evenly.
7. Bake in the preheated oven for 20 minutes, stirring halfway through to ensure even cooking.
8. Once done, pile the mushroom mixture onto toasted buns and top with cole slaw if desired. Serve immediately.
