I hiked nearly halfway before meeting a guy who always hiked with a loak of bread and lunch meat. Most people, like me, were on the tuna fish and tortillas lunch plan. Bread doesn't squish as bad as you might think, is actually a decent source of calories and is a hell of a lot easier to find than frickin' tortillas. Lunch meat as in salami and other extremely cured meats last for at least three days with no worries. I personally could never make it past day four w/o finishing of the pound I would buy. That and a block of extra sharp was my lunch and it was a lot better than another packet of tuna.
