It looks like something Aldi in the US would carry, it's pretty common for them to have weird pizzas. Germans, do your grocery stores sell weird pizzas there or is it just something inflicted on the rest of us?
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.
I have no idea why, but my middle school served triangle/cardboard pizza (Tony's, maybe?) and French fries as a meal combo every damn day. My little 12 year old mind couldn't comprehend why they would just let us eat two of the best foods every day for lunch, but I loved it.
Now, I doubt this would taste the same, but it's definitely a good combination.
