Whenever I got sick as a child, I remember being fed macaroni in vegetable broth, with assorted protein and veggie combinations. It was usually frozen peas and strips of ham, and/or an egg.
To this day I can't bear to eat macaroni in any form.
But ever since I was old enough to cook for myself, I quickly discovered a new comfort dish to tide me over any illness--udon in soup.
Start off with a tablespoon of miso in a small pot of boiling water to make the miso soup base, add a packet of udon noodles, small cubes of tofu, enoki mushrooms, dried seaweed, and a sprinkling of furikake or S&B shichimi for a bit of kick. It may not look like a feast, but when I'm a grody wreck from too many long days and late nights or the muthafuckin' flu, it's a godsend to chow down on something that can be cooked in 15 minutes.
