One might not expect a meatless tortilla soup to be very hearty, yet this is actually quite satisfying without animal, or even soy, protein. Pumpkin puree (made from scratch or canned) and cubes of avocado add creamy richness and balance the soup’s tomatoes and spice. Tortillas appear not only as crispy garnish but they are also cooked into the soup, infusing it with texture and flavor.
