Many say there is an obligation to eat meals with bread as part of simchas Yom Tov.
Is there a similar obligation to eat bread during Chol HaMoed? If so, how often? For example, during Chol HaMoed Pesach, must one eat matzah daily?
I can pass along this bit of halacha (I will add bold for the relevant part) which I got in my email:
Every day of Chol Hamoed we add ya'aleh v'yovo in Shemone Esrei and bentching. In Shemone Esrei it is added in the beracha of Retzei before the words v'sechezena eineinu. In bentching it is added in the beracha of Rachem before the words u'vnei Yerushalaim. Shulchan Aruch writes that if someone omitted ya'aleh v'yovo in davening he must repeat Shemone Esrei, but if it was skipped in bentching he does not need to repea tbentching. The Mishnah Berurah explains the difference. Because davening on Chol Hamoed is mandatory, it must be repeated if there is an omission. In contrast, eating bread/matza on Chol Hamoed is not required, so bentching need not be repeated if ya'aleh v'yovo is left out. While according to the Mechaber eating bread/matza is not required, it is proper to do so. There are some Acharonim, including the Gra, who hold that one is required to eat bread/matza on Chol Hamoed. (סעיף ב וס"ק ג; ביאורים ומוספים דרשו, 3)
