I needs to be on super soft Wonder bread. You need to put chips on it, too- preferably Lays (or Vitner's in Chi-town). Mmm...haven't had one in 20 years, at least.
This is how I used to love it too. Bologna and cheese with mayo and smashed potato chips.

Hebrew National used to make it without corn, but I can't find it anywhere in Chicagoland. I used to find it in Ft. Myers when visiting relatives and would eat it for lunch every day on vacation, but the last few times, no joy.
