Obviously what you are eating is not sausage. I have no idea what it really is but it certainly is not sausage. It is some concoction ginned up by some company and called "sausage". If you like it, there is nothing wrong with that, but it isn't sausage. The reason that the company calls it "sausage" is that you probably wouldn't even buy it if they called it something else like "fried plant patties". If you don't want to eat real sausage then don't, but why kid yourself about what that stuff really is. It is all a marketing ploy and has little if anything to do with nutrition or eating healthy.
The main reason I wont eat a meat sausage is just that, because of all the rubbish they put in it. I eat vegetarian sausages because I know what is in them and they taste much nicer.
