@DrewDad,
												Meanwhile, if anyone comes across this via Google in the future, this is what worked well for us:
The big star was/is overcooked, mooshy (NOT al dente) 
macaroni and cheese, with a little extra milk.  This was the first thing she ate in any quantity, and it's still what I give her if she's a little sore.
Overcooked 
pasta with Alfredo sauce  offered a variation on a theme.
She also had a lot of 
scrambled eggs early on.
Soft (slightly melted) 
vanilla ice cream was one of the first things she could eat/drink/ingest.
Jello was very, very useful for getting fluids into her when she had a really hard time drinking.  When I felt she hadn't had enough fluids I'd set her up with a book or a computer game (something distracting) and then just spoon a bowl's worth into her, using a small spoon.
Strawberry syrup -- the kind sold next to chocolate syrup -- used to make 
strawberry-flavored milk  worked well a bit later in her recovery.
Smoothies did NOT work for her, and I never figured out why.  The first was made with a bit of mango and I thought that might be the problem.  (Other ingredients -- banana, yogurt, milk.)  The next had no mango but still made her throat hurt -- I thought it might be from using the straw, having to work a bit to ingest.  The third had no mango and I gave her a spoon, not a straw -- still hurt her throat after a few spoonfuls.  She had a banana without much problem, so maybe the yogurt was the issue?  Dunno.
Also, any kind of hard popsicles were a bust.  Like those fancy chamomile tea ones I made -- didn't work.  The only ones she liked were smooth/ creamy and soft.
Chicken soup with matzo balls was tried a bit too early I think but it was one of the first food-food (as opposed to dessert) items she could tolerate.
Pudding!  Wonderful stuff.  Second only to jello.  Chocolate, vanilla, tapioca.
Very ripe avocado was a good way to get some veggies/ healthy stuff into her.
Mashed sweet potatoes were another way.
Tried lots of other things -- some successes, some failures -- but those were the main things that a) were really useful or b) were a surprise failure.
