A prayer before eating bread

Hi,

One may not add prayers after washing for bread and before the "HaMotzi", even if those prayers relate to the meal itself. At best this is an interruption between washing and HaMotzi, and at worst, if the prayer is intended to be a regular service, it is also a violation of "Bal Tosif", the prohibition against adding regular prayer.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 2:48)

Have a great day,
Mordechai
