Not much you are going to eat to get rid of sore muscles after the fact. The lactate acid is in there and needs to be pushed out. You can take 5-8g of glutamine after working out and will help in recovery.
I do what I call a "regen" workout after any intense exercise which consists of using a foam roller and a set of tennis balls to massage the body. You can get a better effect by getting some hot chick to give you a massage (Texas Massage Institute trains there graduates on real bodies and it costs about $25 for an hour)
