Erev Pesach is on Shabbat. Can still use challah for Shabbat lunch?

this year a of PES falls on chabas what should we eat this year the issue is that we can't eat matah because one's not allowed to eat matah on to eat then you end up with in your house some people will eat Kal and they will calculate exact amount that they'll need for their family and they'll set aside that amount that isn't going to be sold with the rabbi some people will use egg matah the advantage of egg matah is that it's not humit in case there's crumbs around the house it won't be an issue on the other hand you have to eat more of it according to some opinions you should eat about two egg matzas per person at the meal in order that it should constitute a meal because egg mat is not really considered bread unless you eat it together with a meal in a certain proportion although egg matah is not humet by ashaz unless the person is elderly or sick they should not eat it after the time when Kus is not eaten in New York it's about 10:20 or 10:40 depending on which time you go with at that time a person should make sure to finish his meal at least the eggs a part of the meal he should not eat it after that point
