This soup has a really flavorful broth that goes well with other hearty vegetables. Try adding some extra veggies like green beans, shredded Brussel sprouts, celery stalks, bell pepper, asparagus, parsnips, spinach, broccoli florets, or kale. This is a great way to use up leftover veggies from the fridge before they go bad! Root veggies and cruciferous veggies work really well in this recipe.
