Q. ( Re-question 2660 above - This year (5780) Pesach Sheni falls on Erev Shabbos). We also have a minhag to eat an egg and maror, at that time. Should we do so on Leil Shabbos (Friday night)?
Is there a prohibition to eat on that Shabbos seuda roasted meat, as there is in the Pesach seder?
A. On question 2174 in regard to eating eating maror and an egg on Pesach Sheni with the matza, we wrote: "Piskei Teshuvos (492: n. 11) and Nitei Gavriel (Pesach 3: 57: n. 14) quote this minhag from Devar Yehoshua, Darchei Chaim Veshalom and others.
They add that some Chassidik Rebbes have a minhag to have a “Tish” and celebrate a seder on Pesach Sheni and indeed eat besides the matza, also maror and eggs. They mention that this is the minhag of Chabad, Belz, Satmar, Spinka and others, each with their own particular variations. They point out that in Nad’vorna they drink also four cups of wine.
Horav Shlomo Miller’s Shlit’a opinion is that one should maintain his own minhogim and traditions."
On question 2175 regarding roasting meat for the Pesach Sheni seuda, we wrote: "Rivevos Efraim (2: 138) and Bein Pesach L’Shavuos (7:14) write that one should be careful when buying meat, not to say that it is for Pesach Sheni.
Rashash (Pesachim 53a) maintains that one should also abstain from eating roasted meat. However, Chazon Ovadiya (2: p. 178) asserts that one can be lenient, but should avoid roasting a complete animal, similar to the Korban Pesach.
Horav Shlomo Miller’s Shlit’a opinion is that one can be lenient."
On this year, when the Pesach Sheni seuda for those who keep the minhag is on Leil Shabbos, Horav Shlomo Miller's opinion is that one can definitely be lenient.
