I'm guessing Italian Spices in the sausage. Since it was mild, I'd go easy. If you don't have a container of Italian Spice, I'd use Lawry's Season Salt or such and maybe a little oregano. I think this would also taste good with a garlic or onion sausage, so you could always use whatever sounds good to you at the time.
Like Padrefan, mine was flat and 2" all the way.
