It's very interesting to take apart some typical American fast food like McDonalds or Subway and taste it bit by bit, cleansing your pallet as you go. The bread is literally as sweet as an iced bun or something. Most of the individual components are tasteless with only things like sauces and pickles providing flavour. I've noticed the same thing in supermarket sandwiches and things in the UK. The one place I haven't noticed it is France. You can buy a sandwich from a railway station or something there and it will actually taste good.
