Logging plane food (on a flight)

I'm flying from UK to Abu Dhabi in a couple of weeks and will be given meals on the flight as it is 7 hours. Has anyone on here logged plane food before? If so, how and what did you log?
In Abu Dhabi I will be able to keep up to date with MFP as I have wireless at my dads (where I'm staying) and he has a gym and pool at his apartment so my exercise will go up which is great!
