I'd say it's "try to make use of" rather than eat.
When you buy a leg of lamb do you ask for the eyeballs and tongue?

If it tastes okay, why not, fat meat actually has more flavour than a lean one anyway

Pretty sure they did. It's a modern thing to not eat all of the animal, in the past anything that couldn't be eaten 'as is' would have been minced and made into sausages or similar.

When did any of our ancestors ever eat the bones, or the skin, or the hoofs etc?

Perhaps you think I'm being pedantic. In which case, consider the use of modern technology such as the high pressure forcing of bones and attached tissue through a sieve (Mechanically Separated Meat) or the "pink slime" created with the use of centrifuges. None of these things were available to our ancestors, even those recent enough to have been making sausages!

That's just modern efficiency. Bones from middens do show scrape marks that would indicate lower tech approaches to recovering every possible scrap of meat. I guess it's somewhat ironic that modern living means we can be both more efficient at meat production and also more wasteful.

Well obviously they didn't have all the modern methods we had, but rest assured if they had they would have used them.

It's a common myth that our "ancestors" (despite the massively wide spectrum of different human cultures and societies across the world) were so much more efficient and less wasteful than us when it came to stuff like this. The fact is, on the whole, we've always been a wasteful species who would eat the stuff we like and toss what we didn't.

Thats a burger butty not a kebab as there is no kebab meat in it

You do know who the OP is? You are being wound up

It's one of those things.. It depends. Some of it comes from the myths of the 'noble savage' and romanticised versions of peoples like the American Indians. So when they were confined to reservations, they didn't do so well having not been quite as good at the whole sustainable living thing.. and of course that wasn't helped by being stuck on some bad lands either. If stuff was abundant, then there's less need to minimise waste, and then as preservation methods got better, we could be more choosy about what got preserved.

I live in a rural area where there is one small supermarket with limited choice. Spent an age today perusing the cold meats. It was all made/formed from gunk masquerading as proper ham, chicken etc. Nasty nasty stuff

Depends which part of the world you are in or where you are taking inspiration from.
Many people would describe it as a kofta.

I wouldn't call something in pitta bread a 'butty' personally.

I would never eat economy beef burgers. We only use best mince and by preference prefer to chop our own braising steak. It's not about cheapness.

Decent mince is only about £3 a pound. How little do you want to pay?

Thankfully, he's been banned.
