How do you eat your sandwich?? It was the subject of a story on NPR one time.... Read or listen here I usually have mine RECTANGLE!! (Although when i eat @ this Diner they usually do it in triangles!! (Ah man!!)) Last one I had was a Grilled Cheese sandwich
I usually use a bread roll or a baguette to make a sandwich. They are neither triangle nor rectangle.
Usually just slap it together i havent cut my sandwhiches since i was a kid or if i make one for my kid then yes i usually make her triangles..
