JessH:You CAN still take food on the plane. If your food has any part that could be considered a liquid or a gel it might not be allowed due to the new liquid restrictions. Because of this there were a number of notices sent out warning about many pies, etc not being allowed as carry ons. This has caused some confusion but as long as your food doesn't consist of a liquid or gel you should be allowed to carry it on. There is one other reason that you might be told you can not take your food through security and that is if they think it is going to make a mess in the x-ray machine. As long as you don't try to put your unpacked sandwhich on the conveyor belt you should have no problem.
I have recently taken fresh fruit, pastries, and cliff bars on planes with out any problem.

That will work until someone tries to blow up a plane with an exploding banana or a salami with a bomb in it, I guess...
