Based on my observations of watching other people play, mealtimes on long rests seem to fall into a couple common categories.

Catergory 1: Drink your dinner. You can collect an absurd amount of wine and other booze, and you can just select wine as a meal. It's not called an adventuring party for no reason.

Category 2: Cheese. Everyone gets a whole wheel of cheese. What you do with it is up to you.

Category 3: Potatoes. Just potatoes.

Category 4: Sausage party. No that's no a euphemism, or is it....


And then maybe when you are all out of booze and wheels of cheese you might have to create an actually balanced meal, except that it seems like you could have booze for almost every meal and never run out.
