I am having my surgery January 29, 2015. I have been trying diffident foods to find out what I like for the pre-op diet. I came across Millie's Savory Teas Sipping Broth. I really like them. They are less than 20 calories per serving. And it can be part of your clear liquid diet before and after surgery. I just wanted to post for people who are looking for things to try.
