Cook meals to handle the hunger of your characters. Each mealrequires some ingredients such as water from a well, wood, and raw food.
For cooking, you need to build a fireplace.
Once it is built, and you checkmark meals you want to cook, they will light the fireplace and cook the meal automatically.
Don't forget to build a bench so that your mutants can sit and eat.
Simple vegetables such as carrots or cabbage can be eaten directly when the character is extremely hungry.
And lastly, your mutants will consume food anywhere if they are starving.
