Meat is the most delicious thing I eat in a day. I try to eat some everyday. Mushrooms get close but if you really want delicious vegetables you have to add a lot of dairy based fat and it’s still nowhere near as delicious as meat.
Recipes like yotam otolenghis courgette terrine with tomato chutney is simply awesome. https://www.theguardian.com/food/2020/sep/26/yotam-ottolengh...
I also replaced steak burgers with beyond burgers or similar and I don't notice the difference. I still miss meat sometimes but I eat for special occasions or barbeques.
I'm not sure if it was any kind of standard thing because I've never had something elsewhere called "palak" or "saag" that was similar. Most places in my area have something more creamy, which this was not.
My point is, no matter how good the vegetables are, if I don't have to choose between vegetables and meat, I won't.
It's not like it's hard, if you change what you eat in a few months your tastes and cravings change and you like the new thing just as much as the old thing. But people seem to just get stuck at "but I like this"
