Once again minhagim shonim. My family did not and does not split meals. it was either milchigs or fleishigs. However, the RAMAH states 494:3 OICHLIM MAACHAL CHALAV VACHAR KACH MAACHAL BASAR UZTRICHIM LHAVI EMAHEM BEIS LECHEM AHL HASHULCHAN. I once heard from a rav in my community that the minhag in Hungary was that the night meals were milchigs and the day meals fleishigs but I know people of hungarian descent who are not noheig that way.

NOTICE THE RAMAH SAYS CHALAV not gevina.
I dont know anyone who holds milk to be chamar medina.
why would pizza not be “yom tov�dik”? what about baked ziti, lasagne eggplant? my family has enjoyed all of these on shavuous along with blintzes and cheesecake.
