Preheat your oven to 350°F (175°C) and grease a loaf pan.

In a large mixing bowl, combine the flour, sugar, baking soda, and salt.

Stir in the chopped pecans.

In another bowl, whisk together the buttermilk, vegetable oil, vanilla extract, and eggs.

Combine the wet ingredients with the dry ingredients, mixing until just blended.

Pour the batter into the prepared loaf pan.

Bake for about 50-60 minutes, or until a toothpick inserted in the center comes out clean.

Allow to cool before slicing.
