Mac and cheese never tasted better than this version! OK it's not super healthy, but add the veggies and do what you can!
I'll be honest, I could never get away with it when the kids were young. I'd serve it plain for them.
Then I'd add the vegetables for my own sake. Sometimes I subsitute skim or almond milk for whole milk. And if you really want to cut calories you can skip the butter.... but WHY?
