Lemony Lentil Soup with Collards

Lemony Lentil Soup with Collards
You don't need broth for this lentil soup recipe--it's rich thanks to the browned bits in the bottom of the pan that meld into the soup, packing it with flavor. Ground coriander, from the seed of the cilantro plant, has a floral, citrusy flavor that dovetails nicely with the lemon.
