I grew up in a Mediterrannean country. If you think about it, that's the one region in the entire world that has so many different nations famous for their cuisines: Spain, Italy, Greece, France, Morocco, Tunisia ... and all of them are 80% technically vegetarian or vegan. Think of Italian cuisine with all its pasta with tomato sauce and olive oil, for example, or the Greek cuisine with all its sea food, the world-famous French cheeses, Moroccan pilafs, etc.
It's funny in a way but most of those are the cuisines of traditionally piss poor people (in Italy, for example, you eat best in the -still- poor South). They say that "need is the mother of invention" and I guess if you can't rely on having steak and fries for breakfast, lunch and dinner, then you really need to get creative if you want to have some pleasure with your food.
It's a real tragedy that in the West being vegan has more or less become synonymous with fake burgers and milk substitutes. There's so many things you can eat that are vegan, or vegetarian, that aren't "fake" anything and don't "substitute" anything, they're just delicious foods in their own right. But then, there are so many people who don't even know how to cook steak and fries to begin with, let alone know how to make a good meal out of some vegetables...
When I make stock at home from vegetable trimmings, I put mushrooms and kombu in. In Japanese cooking those two things make a dashi, which is a base stock for a lot of dishes, but even adding them to regular stocks (or if I’m cooking rice or quinoa or something) by tying a sheet of seaweed around some mushrooms and then pulling it out when the cooking is done, it imparts a lot of glutamate but not an overly seaweed-y flavor. I don’t eat the seaweed or the mushrooms usually (dried shiitakes have a texture I don’t like), I use them only to infuse things.
The range of tastes in mushrooms varies a lot more than most people realise - it drives me crazy how many English words are used for the same mushroom (portobello, white, brown, chestnut, crimini, champignon all refer to agaricus bisporus), and how few mushroom varieties most people have tasted.
Especially as A.bisporus is one of the most boring mushrooms in existence.
As in, there exists no delicious food that doesn't contain animal products?
All of the cultures that have long food histories mostly not based around meat must be miserable? Nobody could possibly enjoy vegetable pad thai or chana masala? French fries?
I also said tofu which tastes great and is neither seafood or meat.
