The Leniency of Shalosh Seudos

We left off last week mentioning the leniency of using only one loaf of bread for shalosh seudas. Is there room for one to be even more lenient? The Shulchan Aruch (Rav Yosef Karo) writes that there are those that allow one to eat Mezonos type foods for shalosh seudos, and there are those that further allow filling shehakol type foods ( meat, fish, etc.) and finally there are those that even allow eating fruit. So which do we follow? The Mishnah Brurah (Rav Yisroel Meir Kagen) writes that this whole discussion stems from one simple point. Everyone agrees that ideally you should use bread. However, by the times Shalosh seudas rolls around one usually finds himself stuffed and not in the mood to eat. Furthermore we know that eating when not hungry is not considered eating for a mitzvah, and is often a serious infraction (too much football in my head). So one should try to get as high on the shalosh seudas food chain (someone should illustrate this and send it out to the yeshivas and day schools) as possible without disgusting himself and his stomach. Next week we will discuss the proper time for shalosh seudas. If anyone has any suggestions comments etc for future HalachaBoy I am listening and interested. Don't be shy- no topic is to daring, no discussion to hairy, no inyan to scary for ..... HALACHABOY....(dramatic ain't it?) Last week's Q of the W- What halacha do we learn from the mon? Congrats to the Royal Queens Doctor for answering that one reason we cover the challah to resemble the mon that was covered with a layer of dew on top and on bottom. This Week's Q of the W- We just mentioned the serious sin of eating when not hungry. What day of the year does Chazal wave this aveirah and award a mitzvah for every bite, even if not hungry?
