Food is eaten to restore health and stave off hunger. Each party member generally consumes 1 unit per meal. It can be purchased in the Provisions menu just before Embark for 75 gold. When "Hunger" is activated one food will be used per party member - the exception to this is if a party member has a quirk or trinket that alters how much they eat. Healing out of combat can only be done by feeding food directly to a wounded hero.
