Hi @Jovdp - so sorry to hear of your mouth ulcers. :( I hope it settles down soon.
I used to work in a major hospital, preparing food for patients who’d had mouth surgery ... so needed liquid diets.
You can turn lots of meals into soft/mushy/liquid meals by putting them thru a food processor/blender/kitchen whizz. The only down side is that if you mix everything up, you don’t get the specific flavours ... but if you whizz them separately and serve them on a plate, you do (but it takes longer to prepare!). I used to whizz up roast dinners (meat cut up into tiny bits and whizzed with roast veg using lots of gravy and mint sauce for lamb) or casseroles/curries (which usually have enough liquid in them.) Obviously, drier meats (like steak) wouldn’t whizz up without being cut really small and added to a liquid base .... so casseroles or pie fillings would be the way to go. Steak & Kidney! YUM!
Tinned fruits work really well, for a sweet alternative .... they usually have plenty of juice so whizz easily (you could even freeze them in an ice block mould to turn them into a yummy fruit ice block or paddle pop - which may even help soothe the ulcer.). Tinned Peach and ‘Rice Cream’ is a delicious mix ....
Even a decent milkshake, using an egg, banana (or apple and peach) with vanilla and milk and all whizzed up is a pleasant, easy, healthy drink/meal replacement. You can add custard or cream or ice cream to ‘value add’ o the flavours .... or add a bit of Baileys Irish Cream for a bit of decadence ;)
Be inventive .... what are your favourite meals? Can you add some sort of liquid to whizz it up - or even partially process it so it is easier for you to eat?
You could make up Bolognaise and whizz it to get rid of lumps .... you could deliberately overlook the pasta so it is really soft so easier to eat with it, if you don’t fancy whizzing it all up together.
if you go for the more liquid foods - get a really wide straw (so you can suck it up past the ulcer, so it doesn’t aggravate it. Big W has ‘jumbo’ paper straws or Bunnings or similar would have stainless steel jumbo straws that would be machine washable .... or get them online ..
Good luck, all the best for the rest of your chemo xx
