Preheat oven to 425 degrees.

Line a cookie sheet with parchment paper.

Whisk flour, baking soda, baking powder and salt together in a medium sized bowl. Add cheese and herbs. Mix until well distributed.

Combine egg and buttermilk. Whisk with a fork.

Make a well in the center of dry ingredients. Pour in wet ingredients. Stir just until flour is incorporated. Be careful not to overwork the dough.

Add a tablespoon of flour if needed. The dough will be sticky, however you should be able to work it into a mass.

Place dough onto a floured surface. Dust dough with additional flour and work gently and quickly into a round loaf.

Transfer loaf onto parchment paper. With a sharp serrated knife, cut an 'X' into the top of the loaf.

Bake for 20 minutes. Remove and cover with foil. Bake an additional 7-10 minutes or until golden brown.

Brush loaf with melted butter and sprinkle with sea salt (optional).

Allow to cool for 15-20 minutes.

Best eaten fresh and dipped into stews or soups.
