For an all dayer I take a sandich of some kind (nuthin messy), maybe an apple, some jerky if I've made some, maybe some sausage biscuits, and definitely some real basic trail mix (I just mix some nuts, cashews or peanuts, with peanut M+Ms).

I dunno what you're hunting, but what you should consider is packaging---how much noise are you gonna make getting all this grub open---and placement---how much movement is it gonna take to get it in your gullet. I made a few real basic chow bags, they're basically cotton cloth something along the lines of linen, with a long (mabye 7-8") flap. Anything that has a noisy wrapper, I take out of that wrapper and put it in this bag. The long flap allows me to roll it up kinda like a burrito for carrying in a pocket or pack. It's real quiet in the woods.

Good luck and don't go hungry! Oh, by the way, you may think you're only goin' for a few hours, but what if you break a leg or some dumbass shoots you? You might want some extra chow while you're hanging out there.
