Thats why there are cooks.
No, can you reliably conclude that based on your own anecdotal evidence?
Yes some expats are straight from das vaterland and would expect knoodlen (yummy) and lederhosen but these days it's more than likely that they've had a broad culinary exposure right in their home town too, where "arme ritter" French toast is also a favourite.
Because you don't know what it is means......you eat healthily no doubt, frying not for you, you're from Groningen your staple is cheese?
