Not surprised. Vegetarianism has been the default in India for ages.
They’ve greatly explored the spice palette and can make pretty much anything taste amazing.
EDIT: some clarification. I did not mean to imply that majority of Indians are vegetarian. No. Majority do eat meat.
But in most parts of India they do not eat meat on a daily basis. It’s typically a once a week kind of thing. And yes, I’ve observed this among friends and colleagues from practically all parts of India. Even the most fierce non-veg fiends will typically do a weekend bash, but eat regular roti sabzi, dal chawal rest of the week.
