Siman 300
Presented here for study, not as a practical ruling. The Shulchan Aruch rules by Sephardi custom, the Rema's glosses by Ashkenazi custom, and the Kitzur follows Ashkenazi custom. For a practical question, ask your rabbi.
א לְעוֹלָם יְסַדֵּר אָדָם שֻׁלְחָנוֹ בְּמוֹצָאֵי שַׁבָּת כְּדֵי לְלַוּוֹת אֶת הַשַּׁבָּת, אֲפִלּוּ אֵינוֹ צָרִיךְ אֶלָּא לְכַזַּיִת.
1 A person must always arrange his table Saturday night (see Shabbos 119b) in order to escort the Shabbat (out), even though he will only partake of an olive-sized portion.
