don't expect a "meal". On short flights, outside of established "meal times", you're likely only to be offered a 25g pack of something either sweet or savoury. Even at "meal times", the most you're likely to be offered on a short flight is a (sometimes unappealing) small sandwich.

If you're hungry, consider eating on the ground between flights (though food at Schiphol can be rather expensive) if you can't wait til you arrive at your final destination. You can also bring food purchased at Schiphol on board with you - just be careful with buying liquids. Depending on your destination (all non-Schengen flights - which includes the UK, for example) there will be a security check either at, or just prior to, your gate for the shorthaul flight. Any liquids that don't comply with the EU security rules will be confiscated - but you can ask the shop selling you your bottle of water, etc, to seal it in a clear plastic bag which should remain sealed until you have cleared security.

Drinks on board are free (even beer/wine) but the serving sizes for soft drinks, juices, and water are tiny, so you may wish to also bring your own drinks, to supplement that which you will be given onboard, if you are bringing your own food.
