With DD, I had a really big lunch out with DH, and birthed by 6:30, so I didn't miss a meal. With DS, I had a big dinner out, and birthed him before breakfast, so again, didn't miss a meal. Hmm.... I'm sensing a pattern.... eat out a meal, have a baby.... 
I drank gatorade during both labors, and had some dried apple with my second labor, maybe some granola bars? Can't quite remember. But, it was nice to have some food on hand. DH really appreciated it too! He gets terribly cranky when he gets hungry, so I'll make sure I've packed enough to keep him a happy labor companion!
Most people who I know who have birthed at the same hospital as us rave about how good their food is. We've never stayed long enough to really appreciate the food, but I guess at least its not horrible!
I think I will pack:
dried cranberries, fruit etc
protein bars
pretzels
gatorade
Thinking also about making some pumpkin bread cupcakes and freezing those. Someone mentioned cheese and hard boiled eggs, and now those sound good, too! I'm getting hungry....
