A very traditional Dutch food in the Netherlands, Hollandse nieuwe haring should be tried at least once. The raw herring fish is typically served with chopped onions, and can be eaten with or without bread. Herring should only be called Hollandse nieuwe if caught between May and July.
They also eat Poffertjes, appeltaart, Bitterballen, Rookworst, Stroopwafels, Hollandse Nieuwe Haring, Goudse Kaas, Chocoladeletters, Drop.
They drink Koffie Verkeerd and more stuff too
hope this helps
