How Did U.S. Wartime Rationing Change What Families Ate at Home?

During the Second World War, rationing affected household shopping as well as supplies for the military. I’m curious about how those rules changed ordinary meals in the United States, beyond the familiar idea of saving sugar or meat.

Did families mainly substitute ingredients, grow more food themselves, or change how they planned meals? I’d also like to know whether these habits lasted after ration books were no longer needed.
