The day before Yom Kippur is considered a semi-Yom Tov, and it is a mitzvah to eat two festive meals on  this day.  Indeed, Rabbi Chiya said “One who eats on Erev Yom Kippur is considered by the Torah as meritorious as if he fasted on both the ninth and the tenth of Tishrei.” ~ Berachos 5b

A G’mar Chasima Tovah to you and your family!
