I eat Quorn several times a week and love it! Their website and cookbook has some great recipes and it is low in fat and a good source of protein.
I usually do a bulk cook of chilli, sausage casserole, mince & veg, bolognese etc. and freeze portions.
I also do loads of stir-fries, curries etc. I find the sausages, burgers etc can be a little dry if you overcook them so usually do them in a lidded pan to keep the moisture in.
The also do a lot of ready meals now and if you compare calories. fat etc with the meat version, you will see a huge difference.
I've found that basically any meat recipe can be replace with a Quorn equivalent.
Have a look at their website - hope you enjoy the recipes!
Just edited to say that I just noticed you were one of Mr Ammori's bypassers too! - He is just fantastic and I hope you've had as good a journey as I've had after my op with him - your stats are very impressive - good luck!
