Mediterranean Cabbage Sweet Potato Soup with Tarragon
It is a tomato-based soup with crunchy shredded cabbage and tender sweet potatoes. To give it a light, refreshing Mediterranean vibe, we added fennel and celery and seasoned it with lemon and tarragon. If you love veggie-only soups, you'll love this cabbage sweet potato soup as well.
Shred the cabbage using a mandolin or just cut them into stripes.
Peel and chop the onion and garlic (finely).
Wash and cut the fennel. Chop off the green fronds, and use only the white bulb part. Cut them in half and then slice one half like you would slice and onion.
Wash and slice the celery stalks.
Wash and slice the lemon. As we put them in the soup without peeling. Make sure to choose organic ones, or ones where the peel is not treated with chemicals or preservatives.
