I'd suggest picking up some Italian food tastes, simple, quick, and easy to balance. Not as quick as grabbing something ready to eat admittedly. But lets face it, a well balanced meal can be knocked up in less than 20 minutes if you keep it simple. Shame there's 20 minutes of washing up afterwards!

If you are looking for some in depth info I'd recommend Matt Fitzgeralds 'Racing Weight', stacks of info. Possibly too much but there's enough info that you can scan through to get the ball rolling.
