Makes sense mac and cheese is British tho so it'll have to be deep fried and left in the sun to rot then smothered with soul food spices I call it the triple me to the toilet deluxe
Mac and Cheese is literally a bog-standard gratin with Mornay sauce. If the British claim is to have downgraded it by replacing all the veggies with straight carbs then I guess yeah we'll have you let that one.
The modern recipe for the mac and cheese we all love and enjoy nowadays was invented in uk in 1716 invented by a housekeeper and published in her book The Experienced English Housekeeper.
No. Well maybe in the Anglosphere. In Germany you're more likely to see Gratin de chou-fleur, that is, broadly speaking, replace all the macaroni with cauliflower, than Mac&Cheese. If you're being lazy just use a package of frozen veggies, those cauliflower-carrot-pea-butter-spices boxes. Add a potato or two if you want carbs. If you want cheesy comfort pasta there's either proper Carbonara, or a cream and cheese sauce, more or less exactly South Tyrol style.
