Almost everyone I know prepares Kraft Dinner a little differently. For example, DD and DS like it with a bit of Cheez Whiz added to the regular way.
I, on the other hand, prepare it the regular way except for the last step. I do not put the cheese in and stir it up, I sprinke it on the noodles just as I would any other pasta.
Some people put ketchup in theirs.
How do you prepare it? Let me know your twist on this favorite.
