Is it permitted by our tradition to eat religious meals of the nations? For example, Ashure (Noah's pudding) of the Muslims, Kutia of the Polish and Ukrainian Christians, painted eggs of the Russian Christians, sweets of the Vaishnavs (Krishnaism) and turkey of the Protestants.
I'm trying to avoid eating such meals, especially on their holidays. The main reason is to distinguish, and not to confuse anyone, thinking it's ok to join their celebrations even by eating similar meal on the same day.
But is it really that strict in Halacha or a minhag?
