I agree the food itself is pretty bleak. But this resonates with me because I have a fond memory of a rushed meal after a surf with my father.
We were on a camping trip so all we had in the car was two small cans of tuna and some multigrain bread. After getting out of the water and feeling completely exhausted, there was something satisfying about slapping the contents of the can onto a slice of bread and biting into the most basic meal imaginable.
