Mac n cheese is the ultimate comfort food at any time of year. In winter, it hits an even sweeter spot. This veg, boosted twist offers the same look and texture, to my mind, as boxes of Kraft did when I was a child growing up in America. We ate a lot of amazing homegrown food cooked from scratch, but there were also plenty of packets and boxes such as Hamburger Helper and crinkly foil, wrapped parcels of bone, dry waves of ramen noodles with their tiny sachets of salty seasoning. This mac dishes out a rich lick of nostalgia, but, to go with it, there’s a delicious dose of immune, boosting nutrients, too.
