Dear Rabbi Simon,
Am I allowed to eat leftover Matzah from Pesach instead of bread for Shabbos?
Matt
Hi Matt,
Sure. There is no objection to using matzah (in place of challah) for Shabbos. Use whole rather than broken pieces to fulfil the mitzvah requirement of lehem mishneh.
By the way, there are those who have the minhag of using matzah for (part of) lehem mishneh every Shabbos between Pesach and Shavuot in order to emphasise the connection between the Redemption from Egypt and the Receiving of the Torah. This itself is (or would seem to be) the meaning/purpose/significance of Counting the ‘Omer day by day. Enjoy the crunch.
Best wishes
Rabbi Rashi Simon
