you don't need cheese for a ham sandwich. a bit of lettuce, butter, pickles and onions with a bit of humus would be fine. for a ham and cheese sandwich, then yes, you do need the cheese. have you consider some kimchee with black forest?
*sorry for side track. please resume the discussion on the nature of power and us human nature. *
Just had some home made kimchee mixed in with potato salad - very interesting taste and very good as well
