Soup (Chicken is good, but, pea soup or some lentil would be my preference... they sell these in a brown bag in the soup aisle at most stores. You just boil water and it in, and then at the end, a little olive oil, and it's very good).
If it's a meal time, I also like to throw in some tortellini's. By the digorno or other refridgerated brand, put in some chicken broth and boil for the same amount of time as it says to cook 'em nromally. Add in some carrots and celery if you are feeling up to it. MMmmm.
Keep the liquids coming and going though. Hope you feel better soon!
