Yes, with some (but not enough) extras. More can always be said on the matter if anyone would like to address this topic, so if you reading this right now can contribute, please don't hesitate to do so! More posts are always welcome.

For the meantime, OP, we do have a user flaired in Irish Food History, and thus I present some previous posts by u/gothwalk on the Irish diet:

• On the Irish diet at the time;
• On why the potato became so prominent (adding on to u/Malicous_Latvians);
• On how they were prepared;
• And bonus: on why fishing wasn't an option during the Great Hunger.
