            Anything warm is especially good for morale, including tea and coffee and broth. This especially applies when times are cold, wet, or snowy, and dark, like during security patrols during the cold season.

            Now the expectation of some kind of future food is also good for morale in many circumstances. Hence the chief cook is an important person during hard times, really all times. And it doesn't take much, other than effort and initiative. Food in the belly can go a long way towards  improving the morale of anyone hungry.
