I don't remember exactly, but I know I didn't have any "real" food for the first month. At three weeks, about all I'd suggest is something like applesauce or something pureed. Definitely wait on the salad . . .
The first month or two isn't much fun, really, but it does pass and it gets better. I can eat just about anything now, although not too much, and obviously there are some choices much better than others!
