The topics doesn't come up much, but it has so I must make a few comments. Now strictly, speaking my idea of a sandwich is turkey, lettuce, onions, on a real baguette. Most of my variations involve cheese, peppers, and another meat. Occasionally I make an exception for an Italian style sandwich on focaccia or ciabatta, a gyro, a muffuletta, and once a while a cheeseburgers.
