In a large ovenproof skillet heat oil and butter add sausage stuffed potatos, season lightly with salt and pepper, ( the other seasoning comes at the end.) Add potatos to hot butter/oil mixture and coat well. Tranfer to oven and roast about 1 hour turning to have all sides become golden and crispy, add potato middles now and roast until they are golden and crispy, about 10 minutes. Remove all potatos to a serving dish, sprinke evenly with garlic powder, cajun seasoning, pepper and cheese, add salt to taste.
