My husband and I will be visiting Chicago soon to visit my alma mater. He insists that we MUST eat a particular sausage on a hoagie-type roll he saw while I was watching Oprah. While living in Chi-town, I never had one, so I'm not sure what it is. I vaguely remember seeing it on Oprah that day (she said it was one of her Chicago faves)...it looked like a sausage on a roll, smothered in sauce. I also remember they mentioned on the show that they have them on the south side. It wasn't just a Chicago style hot dog...it looked more like a hoagie with tons of sauce. Any ideas?? Help would be greatly appreciated.
