I understand that point. It is just my wife and myself here. There's lots of stuff we don't cook, because we only eat so much, and the rest is wasted. We feed our gaming group largely so we can play with recipes we couldn't make for just the two of us.
Oh, but then we can also bring up America's Test Kitchen yet again. They do a lot of work downsizing recipes to serve two, which is great.
We make stuff to have leftovers, for lunches during the week (we got three days of lunches after eating the bean stew I posted earlier for dinner). That's part economy and part that there are recipes it's really difficult to cut down.
