Reply To: Milchig Meal on Shavuos

little – ” As for Shalosh Seudos with Divrei Torah, that is the Chabad line. It is unique, and is not accepted elsewhere, not among Poskim, not among Chassidim elsewhere… anyone besides Chabad.”

There is a halachic sefer called Mateh Efrayim (as far as I know, this sefer has nothing to do with Chabad – but I may rarely be wrong) 602:42 that one can rely on divrei Torah when rov gave a long shabbos shuva derasha past the zman to wash,

(In contrast, and for complete disclosure, the Mateh Efrayim himself writes in 597:2 that who are we to compare ourselves to the Rashbi – yo be yotzeh seudah shlishis with divrei torah).

Also Sh”t Tzitz Eliezer vol 17, s. 13.
