Prosciutto and butter sandwich

Here's another sandwich that I first had at 'Wichcraft in Vegas. I mostly got it because it was the cheapest one there. Every sandwich was like more that 7 bucks and this thing was maybe 4 or 5. The combination is good, can't complain about prosciutto and bread and butter are one of my most favorite things in the world. I think supposedly it's sort of a play on the classic ham and cheese sandwich. Whatever I guess. I found a recipe and the people at La Brea bakery also have a sandwich like this. They had an optional scallion and parsley oil to drizzle on top which I made for fun.
