I just cut up some red potatoes in small pieces and some smoked sausage, too. Added the corn and shrimp, seasoned with salt, pepper, and Old Bay, drizzled on a little EVOO, and covered with foil. I had to cut the potatoes pretty small so the would cook and not overcook the shrimp. I had cooked the cobbler first over indirect heat and when I got around to this the coals had cooled off so I cooked direct for about 20-25 minutes.
I cheated on the cobbler and used a can of pie filling. Cooked indirect for 35-40 minutes. Both turned out great!
