I would really like to know how to do that. Gyros sandwiches - or salad made of the same meat - are among our favorites, and we’ve seen recipes by Alton Brown and on Food Wishes - the Food Wishes one looked a lot like the real thing.

If you should have time, could you tell us how you make yours?
Pretty much made the one you post but I’m not a rosemary fan
It’s better if you slow roast a chunk a lamb in your backyard all day basting it with olive oil and many cloves of garlic like my grandfather did. ( The beginning of my foodies roots. Started with his fleeing from the Bolsheviks. The beginnings of my libertarian roots!)
What makes the gyros is the Tzatziki. Putting the cucumber, tons of chopped garlic, and yogurt in a cheese cloth and hang in your fridge overnight is your first step.
I did the Alton Brown recipe and finished it off in the broiler.
I looked at your link and will try his spices next time. I’m also going to buy a rotisserie toaster oven and make it on a spit.
