I am in the minority that I can't stand boxed mac and cheese. I always had such a hard time eating it at friend's houses....i think I mostly hated the clumpy texture My mom made it with a blend of whatever cheese/pasta was available, butter, milk, and fried onions ...delicious. That, along with grilled cheese and Campbell's tomato soup, is what I lived on as a kid.
It seems laughable to change cheese food flakes to be more natural- but since so many kids just live of it (as our stories can attest!) a little bit better is something, right?
