Pasta is good but requires water and boiling...if you're touring where it's readily available, then that's fine.

I highly recommend flour tortillas. They make a good food conduit. You can put peanut butter in them and drop in some dried nuts, granola and dried fruit for your own DIY cliff bar.

You can also use them with salami and cheese, etc.,

I pack hard cheeses (parmesians) and cured meets (proscuiotto, salame, etc.,) because they don't need any refrigeration and keep for several days.

Canned tuna is also nice to have and can also be placed in a tortilla.

I do enjoy a good loaf of bread, but for packing a tortilla is hard to beat!
