Ugh, vegetarian food trying to be meat just tastes like Disappointment.

That said, I've had some really delicious originally-meat-made-vegetarian dishes, but in those cases the cook knew how flavours worked, and also wasn't trying to do one-on-one substitution so the end product wound up being 'really tasty parmentier/lasagna/meatballs that happened to not have meat' rather than 'omg get it away'.
