I'll second some of these thoughts... I have a hard time in the mornings eating, just don't want too which usually pisses off my hiking partners as they know I will bonk quickly... and
I know I will bonk quickly too...
But for lunches, I swear by pepperoni, salami, cheese, sunflower seeds, almonds or cashews, GU, dried fruits, chocolate. Sometimes I will bring along a sandwich or too, Nutella is soooooo tasty, YUM... Pita bread works great in the winter, I even toast mine over the stove if I am using a stove. You never have to worry about that really crumbling. Quick breads are good too, I will sometimes buy the Pillsbury mix, then dump in lots of tasty things to spice it up like chocolate pieces, more dried fruit, nuts, seeds. On over nighters in the winter I will bring along margaine sometimes too, spread a little of that on some quick bread for lunch, and you will be zipping along the trail.
Bringing along a thermos full of hot soup or drinks can do wonders, my trusty thermos bought the farm this past season, it lasted a long time, so time to get a new one.
For lunches, I will also try to take two lunch breaks, sometimes trying to shovel food down my throat just will not work, but a couple of longer then 5 minute breaks does the trick in winter for me.
Catch you later...

PS,
We once had a lunch break while ice climbing, broke out the sandwiches, thermos with tea, some cookies, sitting around like some Englishmen out for a sporting day. Along came two younger, and much more rougher ice climbers, looked at our set up with wide, and I am sure hungry, eyes, and commented about the spread. I mentioned back to them, well just because we were climbing does not mean we cannot be civilized...LOL... And yes, I offered them some cookies.
