I had a version of a Hawaiian in Krakow once that had kiwi instead of pineapple. I was a bit 🤔 when I saw it on the menu, but it was bloody lovely.
Also agree with a PP on the white sauce pizza. I was introduced to this again in Poland, Warsaw this time. It was simple basil and tomato but absolutely divine. Sadly nowhere where I live does white sauce pizza.
I never expected Poland to become my favourite place for pizza 🤤
