I guess "Meat can make a rare appearance" and "very regular" are subjective.

I grew up in a metro area, and can say that my family, relatives, and friends, have had some kind of meat (mainly chicken, beef and pork) at least 3-4 times a week for main course. And curated meat in sandwich snacks again another 3-4 times. I don't think there were many times I have gone more than 1 day without any kind of meat.

And of course as you mentioned every holiday/celebration must have some kind of meat, mostly goat.

And that's before you grow up and start eating out.

That's what I meant "very regular". Maybe by western standards it still isn't too much.
