Ann, your ideas are right on the money. I can't think of much else...

- softened cream cheese
- tofu (boring, but it's soft. )
- quiche

Yvonne's soup sounds good. I would actually toss it in a blender, to make it easier to eat.

If you do indeed have a blender, an icey berry shake would probably feel good on a sore mouth.

Hope everything goes smoothly; take care of yourself!
