I'm not trying to be a smartass..... but what are you really expecting as an answer? You're 38,000 feet in the air. Obviously, you aren't going to be able to leave and get any other food.... and nobody is going to bring you anything other than what is on the plane..... and your tastes are unlikely to change during the flight. So, where does that leave you????? Eat ahead of time or bring your own food seem to be the only options unless someone here has some amazing super powers.
