So sorry to hear about your daughter, I hope her recovery is swift and not too difficult.
Cauliflower soup: This dish is pretty easy, vegan and can serve as a canvas to a lot of different garnishes to add some variability.
Pumpkin soup: We used to make this a lot in our house and we always used 1 large can of plain pumpkin and fake crab. If the crab is still too difficult for eating it can be skipped and I’d probably sub in a little fish sauce for savoriness.
Jook: We make jook for ourselves and others in sickness and health and it also serves as a canvas you can add things to if you wish. In the link is an instant pot version but obviously you can do it on the stove as well. One quibble I have with that recipe is that we tend to use a 10:1 water:rice ratio by volume and it still comes out a little thick. I believe we also cook at pressure for 1 hour to really break it down and you can even blend it a little if you want it even finer. If you don’t want to make stock specifically for this recipe we totally use bouillon and it’s still great.
Split pea soup: Classic split pea soup, you can leave out the ham if that’s an issue and add in other non-textural garnishes like cheese, hot sauce, etc.
