Okay, so it's only tangentially about sandwiches, but this essay from NPR about choosing to "see each others' tears" is worth sharing, especially when it seems like everyone is angry about something lately.

This is where we are right now. Now, we have to choose. We can listen to the shouting or we can choose to see the tears. So if by now you have decided that story of what happened between Trayvon Martin and George Zimmerman is all just media hoo-ha, engineered by professional agitators who have nothing better to do for a living, then you certainly have that choice, but you are choosing not to see the tears.
