The final episode of the Netflix series Ugly Delicious [1] holds a 'face-off' between Asian dumplings and Italian stuffed pasta. Although quite tongue-in-cheek, they mention that similar foods exist in many cultures.

I recommend the series as they tackle themes regarding the prejudice against certain cuisines, as mentioned by OP. Warning, you'll be hungry after and during each episode.
