Let's face it, coming up with an interesting dinner night after night can certainly be a challenge, particularly when time is short and hunger looms large.  Therefore, I think it's time to unlimber an old tried-and-true favorite of mine. This falls under the broad definition, I suppose, of macaroni and cheese.  I'm still laughing over my friend Carroll's pronouncement that macaroni and cheese is perfect for "when I lose my teeth."  This, however, is great for right now--teeth intact--as it appeals to grown-up taste buds and definitely demands the ability to chew.
