Sweet Potato Soup with African Spices, Sweet Potato Leaves & Chickpeas (Vegan)
Inspired by the rare find of sweet potato leaves at our local farmer's market, this warmly spiced, slightly nutty vegan soup combines African spices with potatoes, sweet potatoes, carrots, zucchini, sweet potato leaves, red peppers and chickpeas. Both hearty and light, a little peanut butter highlights the nuttiness of the chickpeas and greens and adds a touch of creaminess to a warm tomato broth spiced with harissa, sumac, cumin, and chili.
Sweet potato leaves look like this:
They have a faintly nutty taste and are best used in soups or stews. They aren't easy to find, however, so feel free to substitute spinach or your favorite greens in this soup recipe. (If you use spinach, you'll want to adjust the cooking time and add it right at the end of the cooking.)
