How do empty nesters deal with over cooking?

So, kids are gone, ex and I are no longer together (hence ex i guess lol) and I still find I over cook, I try to use less but it seems if I cook much more than a box of macaroni its too much. Sure I save leftovers, but one can only eat so much leftovers.

How have you dealt with over cooking? Or maybe I'm the only one?
