Add the chicken, broth, and rice (or rice quinoa blend) to the pot. Bring to a boil, and then reduce the heat to low. Simmer gently for 20 minutes, or as long as it takes to cook the rice blend.

if the soup is thicker than you prefer, add a cup or two of water to make it thinner. Also, taste the soup to see if it needs a little salt. This will depend on how much salt is in your broth.
