"Meet the Breads! Burnt, Cornbread, Baguette, Russian Black, Plain Loaf, Cinnamon Swirl, Bread Ration, Crumpet, and Pretzel.

-Edit-
I've noticed that some people have questioned the choice of bread for each class. I have done my research, so I've put down the reasons for each one.
Pyro: Burnt- Pyro is a fire related class, so having burnt toast would make sense
Engineer: Cornbread- Commonly associated with southern U.S. (Texas an' dem' parts, pardner)
Spy: Baguette- I feel like I shouldn't need to say why
Heavy: Russian Black Bread- The name says it all
Scout: Cinnamon Swirl- Originated in Massachussets
Soldier: Bread Ration- Rations were commonly handed out in wars, and plus the writing on it says 'WARNING: DO NOT TELEPORT' which the Soldier does in the Expiration Date short
Demoman: Crumpet- Originated in Northern England, somewhere around Scotland (P.S. Thanks, Soldierhero)
Medic: Pretzel- I feel like I do not have to explain this
Sniper: Plain Loaf- "I might have figured why the Sniper is just a plain loaf. The English (Brittish) invented sliced bread and Australia and New Zealand used to be English Colonies"(from The Dark Slayer #⑥⑨. Thx m8)

tl;dr just njoy da picture"
