Shulchan Aruch, Orach Chayim, 180:2
שולחן ערוך אורח חיים הלכות בציעת הפת, סעודה, וברכת המזון סימן קפ סעיף ב
(ב) כל מי שאינו משייר פת על שלחנו (ג) אינו רואה סימן ברכה לעולם משנה ברורה סימן קפ דראוי ונכון שיתן להעני הטוב שבשלחן
Anyone that does not leave some bread on their table [following a meal] will never see the sign of a positive blessing. Mishna Berurah, commenting on this statement: It is fitting and proper to give to the poor person the best which is on your table. [Translation by James Bornstein. Edited for gender neutrality]

Suggested Discussion Questions:

1. According to the Shulchan Aruch, why would someone who does not leave bread on their table never see the sign of a positive blessing?

2. What does the Mishna Berurah contribute to this statement?

3. How can we transfer the values communicated in these two texts to the way we consume today?
