Preheat your oven to 375F.
In a small bowl, add the craisins and vinegar and let the craisins soak until they plump up slightly.
Put a heavy bottomed pot or dutch oven on the stove top on medium heat. Brown the butter but adding it and stirring continuously until the color darkens. Add the leeks, celery and fennel seeds and cook until the vegetables are tender, about 5-7 minutes.
Crumble the cornbread into the dutch oven and stir to combine. Add in the craisin mixture, vegetable stock and salt & pepper to taste.
On a parchment lined baking sheet, spread out the cornbread mixture into a thin layer. A thin layer will help maximize browning (the best part!)
Bake at 375F for 30-40 minutes or until golden brown. Remove from the oven and top with the sage and parsley.
Serve warm :)
