i dont think Rabbi Dovid Meisels was saying that one should only eat foods that our ancestors ate. i think that he was saying that the food served at melava malka should be like the food served st the shabbos meals. therefore if one would have sushi at their shabbos meal, they could have sushi at melava malka. as he says “The melava malka meal should have the character of a Shabbos meal”
rema & YYBC: srry, my second post got approved before the first one, so originally you only saw the second post, not the first. but anyways, one should not think that e-cigs are harmless.
