As this thread is full of people who can't or don't use Quorn I will try to answer your question, even though I am not keen on it.
It is a fungus, but do you eat mushrooms? If so, look on it as a kind of mushroom. Blue cheese? That is mouldy.
If you struggle with the texture of Quorn then mix it with something else, lentils or meat maybe. If it is the flavour, add something you like.
I have noticed Quorn has changed in the last few years, since the vegan fad began. I used to buy the fake beef slices which have now vanished, and cannot bear the sweetness of the fake ham, so maybe you are justified in not liking it.
I won't buy McCartney stuff because it is gross and contains palm oil, last time I bought the sausages they were incredibly salty too.
Cauldron is better (although same company as Quorn, or was) I find their stuff is edible.
Other vegan processed stuff is over flavoured to my mind but try a few. I found some packets of dry stuff to make burgers which I plan to use possibly in a different recipe form.
Look for soya mince if you can find it.
I also use lentils, split peas etc. but Quorn is quick to use, although not that cheap any more.
