This healthy, Japanese-inspired chicken noodle soup recipe is made with udon noodles and gets a hit of umami flavor from a swirl of miso at the end. To make the miso easier to stir into the soup, combine a little bit of the hot broth with the thick miso to thin it before adding to the rest of the soup.

French green lentils and black lentils hold up well to long, slow cooking without becoming mushy. Save the rinds from used-up blocks of Parmesan in a resealable plastic bag or tightly sealed container in the refrigerator. They give soup broths a rich, savory flavor.

Water can be heated using coffee mug or small bowl.
