With that warning out of the way, here's a sandwich I ate:
It's the Toasted Chicken Club from Tim Horton's: whole wheat bun, chicken breast, bacon, lettuce, tomato, some weird honey mustard dressing, pretty straightforward, except that it was really awful. The chicken and bacon tasted really microwavey, almost like they were microwaved and not toasted at all. Also, everything about this sandwich seemed oddly small, like they shrunk down a normal sandwich by 25%. The bread was fine, I guess.
Well, there you go, a terrible sandwich I ate. I'm really sorry, I'll try to do better.
