Milk Shakes and Ice Cream taste sooo good after having wisdom teeth taken out (but avoid strawberry shakes that have bits of strawberry in them). The frostys from Wendy's are great too. The cold helps numb the pain. I would stay away from soup though. Don't forget to keep icepacks on your face. I found that bags of frozen peas or corn worked best. It will really help cut down on the swelling.
I had mine taken out about 9 years ago. I had 10 removed, the most he had ever seen, I must be a genius
