I have to be honest, I have (repeatedly) fed friends and family with quorn beef in chillis, home made burgers, spag bol, lasagne, and none of them has ever noticed lol.
The only time anyone was aware was when my mum realised she had no steak mince in the freezer and I was making some mince and onion pies for my dad. He went to his grave not realising he’d eaten a vegan meal lol
