Having been spending $900/year to eat an omnivorous diet, you'd have to be eating a huge amount of meat to save $1K/year by going veg.

I spend roughly four times that, eating an omnivorous diet which, as it happens, does not include any large slabs of meat, and I'm curious to know where the difference lies. If you were specifically working to economise on food outlay, then it would not be a surprise to you that people not trying to economise have room to cut down by $1000 a year. But if you are not, how does your cost come in at less than $3 a day?

I'm in the UK, where food is more expensive than the US, but not four times more expensive, and while I generally shop at the better supermarkets rather than the cheap ones, I have no inclination towards "luxury" goods, and rarely eat out.
