I love soup when I'm not feeling well:

1. Egg drop soup- I use chicken broth and stir in beaten egg
2. Chicken noodles- chicken broth, Shirataki noodles, diced onion/celery and carrot, shredded chicken
3. Italian wedding soup- chicken broth, pre made meatballs (I love the fancy chicken ones in refrigerated section, but you can certainly use beef), chopped celery and onion. I add garlic and a few handfuls of spinach at the end, some chopped up shirataki noodles. Then I top with Parmesan and parsley.
4. Tomato bisque- I just heat one cup chopped canned tomato with 1 c milk sub (I use cashew) a bit of chicken bouillon and a bit of Splenda. It tastes like Campbell's

Too sick to stand to make any of the above (10 minute soups), here are the only commercial options I have found:

1. Progression French onion - 16 net carbs per can, so not terrible. Also tabatchnick has a 10 g one but serving is 1 cup (but comes in frozen pouch, so I just make one. Whereas with progreso, I assume you want whole can).
I add 1.5 provolone or Swiss, too.

2. Progreso light chicken and cheese enchilada- 12 net carbs per can

I also like sf jello- I add scoop of cottage cheese is hungry. Greek yogurt is nice.
Scrambled eggs or omelets are easy on throat.
I love light Swiss miss- 4 net carbs per cup.

Feel better!
