Preheat your oven to 400 F. In a large bowl, combine together the olive oil, paprika, garlic powder, BBQ sauce, and season with salt and pepper to taste. Add the sweet potatoes, Apples and chicken, and stir to coat. Empty the bowl into a casserole dish. Bake in the pre-heated oven for 40 to 45 minutes, stirring every 10-15 minutes. Add the green onions and bacon to the dish and place back in the oven for another 5 minutes to let all the flavors combine.
