Gotta agree with PBJ - it's a staple on my long trips.
I usually tie the loaf of bread on top of my pack in the back to keep it from crushed.
Some folks use tortillas instead of bread - but I'm a purist.

As for pie - there are two places that come to mind.
#1 - The Olollaberry pie at the Davenport cafe - just north of Santa Cruz, Calif.
#2 - Any of the pies at the cafe in Gibbonsville, Idaho - just south of Lost Trail Pass.

Last summer as I was heading up the pass in the evening I though - "I wonder if that cafe has any pie?"
And DID it! Incredible combinations - like peach raspberry, and apple blueberry.
I ordered one piece and she brought out half pieces of two others for me to sample.
They sure weren't frozen, restaurant food service pies.

Just curious - - when I bike alone I rarely cook - often I end up mailing my cooking stuff back home. I just rabbit food it in camp and stop for coffee and company at a cafe in the morning. On a chilly day I may have soup for lunch or dinner. I find cooking a chore when I am biking alone. When I'm with another rider - it's altogether different - - chicken enchiladas a la campstove - - pasta primavera - you name it.
How do others feel about cooking when solo touring?

PS - Added a pic of the Salmon River near Gibbonsville - central Idaho is an overlooked touring mecca.
