I was going to post something like this:
With a 12" round oven baking dish I take one package of Uncle Johns Pride sausage and line the outside with it. In the middle I fill it with small red potato's, corn on the cob and sometimes use parsnips instead of potato's, really can put anything in there. Usually just use garlic powder and cracked black pepper though, trying to cut down on salt. If I'm going to use shrimp I put them in 15 minutes before it is done and do dash those with some Old Bay. 350 for one hour with the lid on. Can make this in 5 minutes.
