Here's a link to the gyro recipe. I'd increase the spice measurements by one teaspoon each and since I like garlic, I'd double the amount of garlic.
The pitas can be found here. I make a double batch of pitas to serve four people and there are never enough. As a matter of fact, I'm in the middle of making another double batch today to take care of the left-overs. :)
Hope you enjoy!
