Delicious! I made mine with chicken, and the only substitution I made was 1/4 cup regular sour cream plus 1/4 cup plain Greek yogurt, because I didn't have lowfat sour cream on hand. This is a hearty and filling soup that is definitely better the next day, after being refrigerated overnight. You may need to add a bit of water when you reheat it as the rice absorbed a lot of the moisture. Definitely a keeper!
