I've never cooked macaroni cheese before. I just thought it was something that your (annoying) sister cooked back in the '70s.
I used wholemeal penne pasta, real parmesan regano, etc so I intended success
first the white sauce.
BBQ'ed the bacon and fried the onion, boiled the pasta.
Full attention and assistance from the first kitchen hand and second kitchen hand.
I loaded a whole lotta cheese and ground pepper on it, then baked it.
Ah ha, then served with a few glasses of vino to add to the ambience of it.
