One of the little grab-n-go Cornell Dining operations near where I work, outside one of the main student dining halls, has two-for-one sandwiches and salads on Friday afternoon, after lunch hours. Got a pair of seitan sandwiches yesterday, and just inhaled one of them before the hockey game. (Mmm, hockey.)
The sandwich was on some cool square roll they also use for their BBQ sandwiches, which I enjoy. I have no idea what kind of bread it is. Gonna find out Monday!
