In reply to:

pie for breakfast

and in Pennsylvania Dutch country, they eat shoofly pie for breakfast (or whatever other kind of pie, chiefly fruit pie, there happens to be). In this, and other rural cultures where heavy meals are needed by people who labor hard, pie is a staple; it's eaten at almost every meal. Cake, on the other hand, is for special occasions.

Regarding fizzy drinks, there is, in NY and northwards, the egg cream, which contains neither egg nor cream, but is basically selzer or carbonated water and chocolate syrup.
