You sound like a great cook. I am too <preens> but - and obviously this isn't an issue for the odd dinner party - the challenge for me isn't making delicious vegan food, it's making delicious vegan food with enough bloody protein to keep us all alive.
I've been to a few 'gourmet' vegan restaurants where the food has been incredible - but barely any flippin protein! I come away thinking 'it's actually not hard to make delicious and/or really fancy vegetable side dishes, but that doth not a meal maketh mate. It's just several fancy side dishes that came to £150.'
Same with Instagram content - sounds amazing, probably tastes amazing, will kill you in a year unless you're scarfing tofu by the handful off camera.
Since I went vegan a few years ago, I've definitely been cooking less 'Frenchy-European' food and more Japanese, Korean, Chinese, SE Asian and middle eastern food. Partly because I try and avoid the fake meat, cream, and generally very processed vegan 'substitutes', and that makes it hard to do classic french-derived stuff that I miss - especially for eg the very quick 'steak and some kind of reduction/cream sauce' stuff. I have recreated Pommes Dauph though which felt like a massive triumph - with a combo of miso, yeast extract, creamed cashews and vinegar to make the garlic-gruyere-cream ... my kitchen is like a laboratory.
