Lemon Chicken Soup

I have been trying to replicate one of my favorite soups (Taziki's). Here is my version. This is a great recipe for a cold day or when someone you love has a cold:

4 boneless skinless chicken breasts
2 cups chicken broth
1/4 cup lemon juice
1 cup white rice
Salt and pepper to taste
1 shake of red pepper flakes
1 Tb dried parsley

Boil 4 chicken breasts in 8 cups of water until cooked through. Remove the chicken breasts and chop; filter the remaining broth into a large bowl (you want to remove the stringy things that remain when boiling the chicken). Return the broth to the pot and add 2 cups of store-bought chicken broth. Add the lemon juice, salt and pepper and rice and cook about 8 minutes over medium heat. Add the cubed chicken, parsley and red pepper flakes and cook for 3-5 minutes (go easy on the flakes--they can really spice it up).
