Bonkboo, I would go with something a little more rich to complement the acidity and fruitiness of the Saison. Maybe circular puff pastry base, some "confit" meat (think Rillette, slice of foie, slice of Boudin noir), something sweet on top (caramelized apple, onion marmelade, ...) and a dusting of the herbs you put in the beer ... Good luck with the "Brew & Chew" and let us know how it turned out ;-)
