The food/supplies system currently marries a complely vestigial and irrelevant mechanic to a lot of tedious and unnecessary inventory busywork.
It's the worst of both worlds, really.
If they want to keep it as it, they could at least take a page from what Lords of Xulima is and make food an "abstract resource" that raise a counter in a corner (already there, incidentally) without all the cluttering inside our bags (and/or the need to juggle things from local inventory to camp chest and viceversa).
And this is pretty much what I am suggesting in this megathread:
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=820599#Post820599Automate the food resources mechanic. Make Survival skill a more valuable skill to have by making it so that when you find food, you make a Survival roll to see how many Camping Supplies you actually glean from said food resource. Add spells like Create Food and Water and Purify Food and Drink to help increase how many Camping Supplies you get from each food item... etc. Then raise the cost of SR and LR so it balances out (or reduce how many food items you actually provide in the game), and viola.
Imagine how this would work in BG3. You find a carrot. You Take it from the barrel. Camping Supplies goes up by 1. No carrot item in your inventory. No added weight. It's like the game auto-Sent To Camp for you and then made it so you could just auto-Pull From Supplies when you rest. You don't have to do anything but pick up the carrot.
Find a pig's head. Counter goes up by 30. No pig's head item in your inventory. Nothing to manage. It's all done for you.
