Where I am from in the Netherlands near the German border, it's mostly margherita, bolognese, quattro stagione, 4 cheeses or Hawaii, nothing like this...surprised there was Dutch language on the box.
Belgians certainly won't have a clue what this 'Belgian style' cuisine is, but Germans and the Dutch apparently think they sprinkle fries on anything. We think of Belgian cuisine as crude cut fries with mayonaise.
