This is so exciting, it's guerrilla veggie cooking.
I've fed Quorn mince to my rabidly carnivorous father before, and he never noticed. My husband's a pesco-vegetarian, so I hardly ever cook with actual minced beef. I'm so used to cooking with Quorn that dishes like spaghetti bolognaise and cottage pie made with real meat no longer taste right to me.
