Check with your dietitian that can eat jello. It's a great food to practise chewing and swallowing. You can make it up by replacing the cold water with ensure. Even better if you can get hold of ensure juice plus.
I treated learning to eat like being a small child. At first we are reliant on liquids only, and then ,with time tears and practise, we gradually move to foods. Everything is in little steps. It's frustrating at times, but you'll find a place that works for you.
How are you at making soups and sauces? You can control thickness, add small lumps of cooked potato or sweet potato, soft cheese or even soft boiled/poached egg at the bottom of the bowl to give you texture and a challenge. I'm happy to share recipes with you and guide you through how to cook them to give you maximum flavour. I am in the UK, so will do my best to source similar ingredients for you.
