Then move back to the pot and mix in.

To keep the sodium in this recipe low, remove the salt from the recipe and use low sodium broth. Just before serving, add the juice of 1/4 lemon to the soup, mix and taste. Then add in more as needed, or serve individual bowls with lemon wedges to add to each serving as needed.
