At the Shabbos meals there is a requirement to wash and eat bread. This poses a challenge this year for the Shabbos day meals, as being that it is Erev Pesach we cannot eat Chometz after the 5th halachic hour, and it is also prohibited to eat Matzah on Erev Pesach (Surely by day after Chatzos and according to many Rishonim from daybreak. Some Poskim even prohibit Matzah on Friday night, the eve of Erev Pesach. See Shu”t Igros Moshe Orach Chaim Vol. 1 Siman 155 at length).
Some Poskim allow using egg matzah (As per the ruling of the Shulchan Aruch Siman 444:1) and many Sephardim follow this ruling, but many Ashkenazim do not accept this solution, as the Rama (ibid.) indicates that the minhag is not to eat egg matzah. Rav Moshe Feinstein Zatzal (Igros Moshe ibid.) rules that egg Matzah is indeed a good option. Households with small children should definitely consider following this ruling, to avoid Chometz crumbs being spread all over the clean-for-Pesach home. Of course, for Halacha L’Ma’aseh every individual should consult their Rav.
If using egg Matzah, even though at other times the bracha may be Mezonos, when using at a meal and being Kovea Seudah on it, it requires washing, Hamotzi and Birchas Hamazon according to everyone. (See Igros Moshe ibid.) Even if using egg Matzah for the meals, it may not be eaten after the 4th hour of the day, for Ashkenazim, and after the 10th hour of the day, for Sephardim who follow the Bet Yosef (See Mishna Berura Siman 271 S”K 21 and Shulchan Aruch Siman 471:2 and Siman 444:1 and Mishna Berura S”K 7)
The prevalent custom in many homes is that they save a small amount of Challah (A little more than a K’beitzah for each person at the meal) and eat it carefully at the onset of the meal, and after it is done and they clean themselves off, they eat the rest of the “Kosher for Pesach” meal. If necessary, the second loaf for Lechem Mishneh may be a Pesach Matzah, which will not be eaten, but care must be taken to wrap it well to avoid making it Chometz. (See Shu”t Teshuvos V’Hanhagos Vol. 2 Siman 211:5. This Matzah is not Muktzeh, as it may be fed to small children. See Rama Siman 471:2)
