DaasYochid -“And as I wrote -Shvus D’shvus would be Mutter since it’s L’zorech Mitzva (Shabbos).
Not if it was an extra tavshil.”
It’s extra for the day, not for the meal!
“No, he might have a Chulent for one day meal and not for the second (Shalosh Seudas).
You have a good imagination, inventing a minhag and tzorech to have cholent for seudah shlishis.”
Not as good as yours – that you equate Mitzva Gemura and Tzorech Mitzva!
Don’t tell me that you believe that you don’t get a Mitzva for eating Chamin during Shalosh Seudas?
“Prove it.
253.”
Noone, but you, learns up 253 as a Mitzva Gemura!
