When someone is a kove’ah a seudah on Mezonos (eating more than daled beitzim) is there a certain amount of time that the seudah has to be eaten within?
Answer:
There is no specific time for this.
Note that one cannot say hamotzi and birkas ha-mazon for four beitzim alone, and one should be concerned for the opinion that a greater amount is required — the amount that one eats for a normal meal (as the Vilna Gaon rules).
Best wishes.
