Most would agree that a Pepsi (Or RC or Dr Pepper) and a Moon Pie is the ultimate redneck breakfast, but another classic is Grits with Coca-Cola Hot Dog Red-Eye Gravy. Red-eye gravy needs Coke and Coffee.
To go upscale, use Country Ham on the side and skip the hot dogs. Here's another classic: Hot Dog Gravy & Biscuits. Everybody loves biscuits and gravy, but spare me the hot dogs.
