Granola Bar

Eat it next to water. The game text for the granola bar promises a small boost to health and hunger and stops there. Unlike the chocolate bar or a can of beans, it never mentions thirst, so it fixes only one of the two bars that usually run low together.

That makes it a good snack for jobs by a river or a lake. You are farming stone along the bank, the hunger bar has gone orange, and the only food on you is a granola bar from a roadside crate. Eat it, drink from the river, keep swinging. Walk into the desert with nothing but bars, though, and you will still be thirsty, so bring a small water bottle for that part.

It comes only from loot and no recipe uses it, so there is nothing to save it for. Ten share one slot, and that is still a slot a fresh spawn could fill with wood. Eat them as they come and leave real meals from the food list for home.
