I don't know if it would pass for real mince, so don't expect it to, iyswim. Just take it as a nice tasty meal in itself.
You can use it as you would normally, in cottage pie, spag bol, chilli con carne, pie fillings etc, just make sure it's seasoned well and has lots of flavoursome ingredients added, as one of the worst things about it is it can be a bit bland.
Also, as it has no fat in it, it can stick to the frying pan, so unless your pan is considerably better than mine, it does need some olive oil and lots of stirring to save it sticking.
And as people have said, it doesn't need as much cooking as real mince, you just fry onion and garlic, chuck in the mince and stir it til the ice crystals have melted all over it, then chuck in your other ingredients and cooking liquids, chopped tomatoes/gravy/chilli, whatever and cook as usual.
If you're looking for non meat dinner ideas, quorn meatballs are delicious, my carnivore dp loves them with tomato and basil sauce and pasta. Also quorn southern fried "chicken style" burgers are almost indistinguishable from the real thing. Fake hotdogs are great because as real hotdogs have such a low actual meat content they're easy to replicate (just make sure you boil them, don't microwave)
Quorn sausages are very low fat and great when you're dieting because they're also very filling. You can also get chicken or beef style pieces for curries etc, and allsorts of other things in supermarkets.
The only thing you need to avoid is the fake bacon. It's not realistic at all, not tasty. At best it's limp strips of soggy ham flavoured cardboard, at worst it's dry bacon flavoured crisp type strips which snap when you eat them. Avoid.
