This recipe arrived with my William Sonoma Magazine and I didn't see another quite like it - it looks so good I'm posting and planning on making these at my next opportunity. With the beer and mustard they sound differant from the other recipes I've seen here. Think they'll go great with a hot panini. YUM! Plan ahead as they need to be in the fridge overnight and this is not counted in prep time.
