Eating Milchigs On Shavous

The Mishna Verura (494 sk 12) says one of the reasons for eating Milchigs on Shavuos

is because after Matan Torah, they couldn’t eat meat, because it was too time consuming.

They would need to shecht, remove the chailev , rinse ,salt and cook in a new pot.

They chose instead milchig.

What's pshat ?

Matan Torah was on Shabbos and couldn’t do all this because of issur Shabbos and not because

of takes too much time

This question was answered by the Chofetz Chaim  himself.

(There exists today, a copy of his hand written answer.)

He answered that the reason he wrote, “they didn’t eat meat

because of lack of time” rather than because of issur

Shabbos, was, he wanted to give reason even according

to the Pirke d’Reb Eliezer who holds that the Torah was

given on Friday.*

*According to the Bavli , Hakol Modim Shebeshabbos Nitna Torah.
