Rather than southern (USA) favorites - i am going to go with a different type of southern favorite (South Africa).
Boerwors --> if you are in Atlanta, you can pick some up at Goldberg's. Its a beef sausage that is spiced perfectly. The stuff is outstanding. You throw it on the grill, let it cook, and enjoy.
Biltong (sp?) --> A south african type of Beef Jerky. You can also pick this up at Goldbergs. Blows Jacks Links or any other type of generic jerky out of the water.
