So far we've had:
Nut loaf - aka meatloaf without the meat.
Veggie sausasages - aka sausages without the meat.
Vegan wellington - beef wellington without the beef.
Several iterations of roast dinner without the roast.
And roast cauliflower - which is, admittedly, not based on a meat dish.
None of the suggestions have any seasoning to speak of. There's half a world out there of cuisines based on mainly vegetarian dishes with interesting combinations of herbs, spices and seasoning. Where are the dhals, the stir-fries, the bhiriyanis? Even, for heaven's sakes, the pestos, the hummouses or the grilled cheeses?
It's enough to make a carnivore continue eating meat!
