Erev Pesah on Shabbat

When the 14th of Nissan occurs on Shabbat we search for Hametz on the 13th and burn everything before Shabbat and we leave over enough food for the first two Shabbat meals for the timing of the third meal is after Mincha time and at that time we are not able to have the meal with either matzah or hametz rather with matzah ashirah (egg matzah) and the meal should be eaten before the tenth hour. Rema: And in our lands where we don't eat matzah ashirah (egg matzah) as said above in section 462:4 we have the third meal with fruit or meat or fish as is found above in 291:5.

It is good to burn [the leaven] on the eve of Sabbath before noon, in order to avoid making the mistake in other years of burning after noon (and on the Sabbath day he should nullify it) (Tur).

After one has eaten the morning meal this Sabbath, he should shake out the table cloth that they ate with, and clean the plates with his finger, and hide them with his other utensils of leaven. And if bread remains, one may give it to a stranger on the condition that he not go out to the public domain with it, [even if that condition is given] dishonestly, and [only bread of] a small amount.

If leaven remains after they ate, he should nullify it and cover it with a vessel, until after the Festival, and burn it.
