A sandwich that has little to no flavor, a sandwich that looks better on the menu than it actually is.
Billiam: "Hey bro, have you had the steak & cheese sandwich from Subway?"

Thackeray: "Why no I haven't, Billiam! I prefer eating good food instead of blandwiches."

Get the blandwich mug.
A bland sandwich, lacking flavour - tastes like dinner at an amish family.
Can be improved with Branston Pickle.
MUM I wanted a sandwich not a blandwich!
Put some mustard on that!
