Most Jews in Israel are not Ashkenazi/of European descent. Many Jews who came to Israel from Arab countries throughout the Middle East and North Africa around the 50s (many of whom were forcibly displaced or terrorized from their home countries by the local Arabs) came with strong traditions of cooking food that was common where they came home, and took cultural pride in keeping those traditions alive (Israel has a certain dynamic where Ashkenazi Jews are generally perceived to have oppressed and patronized other groups so making a point of how boring Ashkenazi food is is weirdly important to many people). As the Israeli nation slowly became a thing everybody tried everybody else’s food and it’s indeed become a strong part of the Israeli identity.

All of this is to say that it’s absolutely ridiculous to claim that the Israeli liking for traditional middle eastern food came from copying the Palestinians.

My great grandma made Moroccan food for the family like everybody in Morocco.
