If there is ever a reason I can't chew, my go-to is mashed potato mixed with baked beans! Or carrot and swede mash.
I was also going to suggest something like Shepherd's pie.
What about risotto?
Supernoodles?
Lentil dahl
Fish like seabass, lemon sole, plaice and sea bream take next-to-no chewing whatsoever. Or salmon if you don't overcook it.
Porridge, Weetabix or Shredded Wheat with hot milk
There's actually quite a lot when you think about it.... You're definitely not limited to soup anyway.
Chocolate maybe? Just suck it.
Custard, yoghurt, milkshakes, ice cream, jelly
Soft fruits.... banana, raspberries...
