If there is only one challah available for a Shabbos is it preferable to make HaMotzi on one complete challah or to break it in half so that there are two pieces for Lechem Mishna?
The Minchas Yitzchok answers that the Rema (OC 291:4) says that even for Seudah Shlishis one should make sure to have at least one whole challah. This implies that it is more important to have a whole challah and not break it into two, as it wouldn't be called Lechem Mishna.
That being said, says the Minchas Yitzchok, we must understand the definition of a whole challah. He says that according to the Netziv, whole means not broken once it is brought in front of you. Therefore the best thing to do is to have someone else break the challah into two outside of the place where the seudah will be held and bring the two pieces to the table. These two pieces would qualify as two whole Lechem Mishna according to the Netziv.
If the challah is already in front of you and it is too late to break, then says the Minchas Yitzchok B'Dieved, you can use a whole Pas HaBa BiKisnin, meaning a mezonos food that you would wash on if you were kovei'a seudah, as the second challah.

mb, Passaic, NJ, 2012-02-14 07:15:02 If someone came late to R' Itzele Volozhiner's table, he would give them two slices of bread for lechem mishnah. I believe this is mentioned in the quoted Netziv.DC, 2012-02-15 06:02:16 Targum Unkelos on the words "Lechem Mishne" in Parshas Beshalach says "Al Chad Trein". According to Unkelos, translating Lechem Mishne as "two" is a mistake. Mishne means "double", or twice as much as you normally have. Thus, breaking a challah into two wouldn't accomplish anything. Taking two slices of bread, however, or two rugelach, or two of anything would accomplish something according to the Targum
