After testing it in patch5 i have to say I like the new system. Healing food was really immersion-breaking for me previously. The new feature fits into the game as there is a lot of food variety in the game, and also the cost can be fine-tuned in future patches based on feedback (even maybe tied to difficulty options if there is the need for that). Its a little bit too permissive for me as is, i played approx. 30 hours and i never ran out of food but the feature itself as implemented felt natural and enjoyable.
Allowing to use supplies from the camp chest seems to be neccessary to have for this though. Some people mentioned cooking things from materials to gain temp special bonuses, that seems to be a nice idea as well.
