Xisco,
do you fly for a Palma-based airline? If so I'm a bit surprised your company hasn't published a procedure for this. At least I would have expected a certain amount of tourism from the Middle East.
In any event, if you do as explained by some of the other people above you should be allright. Essentially, show it to the passenger before you open it, then explain you are going to open it in order to remove the cutlery before you cook it. If they complain (and they shouldn't, by your simply removing the bits that don't go in the oven the meal is still kosher, as long as your hands are clean, but some people are ignorant), ask them if they would like to open it themselves. In general, ask the passenger for advice if in any doubt, most people will be willing to help--the rest can bring their own sandwich next time.
Caveat: Not cabin crew and not religious. Take what I say with a pinch of salt.
Apa, espero que aixo te sigui d'ajuda. Bons vols
Edward,
It's only Thursday today
Don't shoot him down, man. At least he managed to spell it right, must have taken him... well, six days?
