For all my rides up to 6 hours I use an expandable saddle bag (Topeak Medium Aero Wedge Seat Pack) and my jersey pockets.

The food items I carry are mainly powerbars and powergels, which both stand up well to mashing and cramming into tight spaces. I place one of each into a jersey pocket, and any remaining in my saddle bag. I'm tight on storage space with the tools, extra tube, phone, etc.. but it works with all my items strategically placed in the right spots. Though, soon I'll be trying a Profile-Design E-Pack on my bike so I've got my food items right in front of me.
