It's pretty 50/50 in our house. Because I'm a vegetarian and he's a meat eater, I cook different meals anyway.
He likes Quorn mince, so we have the same if I make chilli or spaghetti bolognese. He also likes SW curries if I don't put anything "weird" in them (sweet potato, butternut squash, etc) - I just stick to mushrooms, peppers, Quorn chicken, onions, etc.
Tonight I'm cooking roast potatoes and veg and he's having roast chicken and I'm having Quorn minted lamb steaks.
So yeah, 50/50, lol.
