[Avodah] Rav Melamed: What food obligates you to eat in a Sukkah and when do you say a blessing?

[Ben Waxman]

Two piskei halacha from Rav Melamed:

1) https://ph.yhb.org.il/13-03-04/ : A real meal (eg meat & vegetables 
but one that doesn't include bread or grain) means one must sit in a 
Sukka (ikkar hadin, not just a chumra).

2) https://ph.yhb.org.il/13-03-05/ : One who eats such a meal (again, 
even w/o grain) says the bracha lasheiv b'sukka.

These pages are in Hebrew but Google Translate suffices.
