Food in of itself is a good option - but eating during combat was just not realistic…
It’s a fine balance it’s annoying sending tonnes of food to camp and with supplies you can literally never run out of full rests.
I like the idea maybe increase the amount of food needed from 40 to 100 so it feels like it’s more important.
I think there was some mention of as your camp & characters grow more food gets consumed- I like that idea too.
