There was a little cart on the walkway behind the Turn One stands at Ascot that sold Italian Sausage sandwiches; can't remember the name of it but the smell of those sausages, and the pans of sautéed peppers and onions and Marinara sauce would waft over the stands, and it was impossible to resist. The only thing that's come close for me since then is the Kokomo Pork Chop.
