Suggestions for a liquid diet

My surgeon wants me to be on a liquid diet for the next 2 weeks. My surgery is scheduled for July 30 and I need to lose about 10 pounds. All my surgeon said was to be on a liquid diet for 3 days out of the week and then in the evening I can eat a light meal. Does anyone have any suggestions as to what I should eat? I know that I will get tired of smoothies and protein shakes very quickly. Also of anyone has any suggestions for different protein powders that would be good I would greatly apperciate it

 The pre-op diet I will need to be on for 2 weeks is 2-3 shakes + one 400 calorie meal per day.  My nutritionist suggested fish/shellfish, white meat chicken or turkey and salad.  She also said that I can use frozen meals that meet the calorie requirement in a pinch.  I'm going to try not to do that because of the salt, but I'll have a few available just in case.
