thanks for everyones reply
we do have a fridge but it always full to the brim so i tend to not bother putting anything in there and normally my chicken salad is at room temp but i dont find that a prob. we do have a microwave but its not always active, sometimes the staff room is closed off for certain reasons.
Tonight i made stir fry so made enough to bring in tomo. Might have to do some omlette for some of the days this week. Not only do i want something filling im trying to watch my money as well and having chicken salad everyday isnt cheap for me. Especially because i like roasting chicken and im watching my electric and gas bills. lol
