+1 that, if no other mechanics are changed, the long rest UI should take into account stashed food. We're already at camp, so it's purely a QoL feature to allow players to skip having to manually take food out of the chest.
Of course, a much better solution would be to overhaul the whole food and long resting system, using one of a number of suggestions that have been given elsewhere on the forum (either make food an actually impactful part of gameplay or remove it entirely).
