recipes for someone who has no teeth

My father in law was just told today that he will never be able to have false teeth. He went to a shoddy place that broke his jaw bone and made a mess of his mouth - permanently. So now Mom is pureeing his food - what a pain.

Do you have any suggestions as to what we can feed him? He has become kind of anorexic because he can't have the meat and potatoes meals he grew up with. He's skinny and weak, and 83 this year I think.

What can we feed him? Do you have tasty cream soup recipes he would love? Soft stuff he doesn't have to chew would be great... high nutrition is essential.

Thanks!
