Eating out can by very hard if you are trying to stick to a diet. Before my wedding I underwent a brutal six month period of dieting and excercise...I hated it. One of my saving graces was P.F. Chang's Hot and Sour Soup. It is out of this world good and get this - it only has 89 calories. You heard me right -89 calories. That's less than a can of coke. And what you get for those calories is a hot scrumptous stick to your ribs soup. I have never been wild about tofu but I gobble it up in this soup. Another great thing about this soup is that it's cheap. I think 3 dollars and change. Just try it you won't be dissapointed!
