Melaveh Malkah during the Nine Days

Hi,

We refrain from eating meat during the "Nine Days" period of mourning. Those who normally eat meat for their Melaveh Malkah meal in honor of Shabbat should not do so during the Nine Days, and no hatarat nedarim is required.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 4:21:4)

Have a great day,
Mordechai
