I imagine this map isn't counting legumes/lentils as vegetables. The Indian diet, especially vegetarian, is heavily lentil based. Lots of paneer (basically a cheese that also functions as a tofu-like ingredient for many dishes) too, and of course breads and rice as you mentioned. Also potatoes. I imagine most of those aren't considered vegetables by whatever source this map is using.

EDIT: Also of course India isn't nearly as vegetarian as people imagine. The surveys are kind of variable, but we're reasonably only sure somewhere between 20-30% of Indians are vegetarians per:

• https://en.wikipedia.org/wiki/Vegetarianism_by_country

Idk I saw it on twitter

https://ourworldindata.org/grapher/vegetable-consumption-per-capita betting this is where they sourced it, FAO presents it at the supply level, the per capita figures are probably OWID's doing? Hilariously this probably also means the US figures are even lower due to home food waste not being accounted for

Hindus eat pork

Speaking from experience, the Indian diet is like 90-95% bread or rice and people eat something else (Veggies, Daal or meat) only for flavour. Too many carbs too little protein.
