In recent years, broccoli has shared shelf space with two other similarly named vegetables, Broccolini and broccoli raab. Broccolini is a hybrid of two different types of broccoli, appearing as small florets atop long, thin stems, all of which are edible except the largest, toughest stem ends. (Broccoli raab is actually a relative of the cabbage.) Here it makes a great partner with scallions, also known as spring onions, for a soup that is vibrant green in color and loaded with nutrients, for a healthy and delicious slurp.
