Preheat oven to 300°F; grease a 9x5-inch loaf pan.
In a medium bowl, combine cornmeal mix, sugar, flour, and yeast.
Stir in buttermilk, oil, and egg.
Pour batter into pan, and bake for 1 hour.
Let cool in pan for 10 minutes. Remove from pan, and let cool completely on a wire rack.
Paula Deen's Hint: If you can't find self-rising cornmeal mix, combine 3 tablespoons of all-purpose flour, 1 tablespoon of baking powder, 1/2 teaspoon of salt, and enough cornmeal to fill one cup. This equals one cup of mix.
