In reply to aln:
you dont want to do anything with it you just do with bacon.
id say something along the lines of lightly toasted pumpernickle cut thick, a thin layer of olive oil, said proscuitto cut thin and layered, one or two very thin slices of mozarella, couple of capers, basil leaves, alfalfa and a tiny grating of lime rind. maybe a thin slice of avocado and red onion too.
and not bullshit little tasters, but a serious climber sized sandwich so you can watch your friends pick at snickers bars and gels while you eat it on the hill.
