And while we're talking about Harvest food, I'll remind you about Bounty of the Harvest, a "hidden" quest reward from the Harvest Festival. Blizzard's page only lists the two books as the rewards of the Hero Tribute quests (outside Ironforge and Ogrimmar, for Alliance and Horde), but after finishing those quests, you'll get another reward in the mail-- a horn that conjures four Harvest bread every 12 hours, even after the festival is over. The food grats 2% healing per second while eating, so if you're a Warrior who needs to eat, or a Hunter who has a pet who can eat bread, it's good stuff.
Supposedly the Bread even used to stack with other food, but I just tried it in game, and I had no such luck-- I only had one food buff, and it was the last thing I ate (either the 2% or whatever the other food was). Still, being able to conjure 4 bread in a pinch is always a plus. Harvest food for everyone!
