I found this recipe, entitled "Pork Gyros with Yogurt-Tomato Sauce, Red Onion, and Arugula" on another recipe site some time back. It appeared in the June 2006 issue of Bon Appetit. Ice Cool Kitty posted the recipe for the sauce portion of these gyros, Recipe #386313 386313. Please see her recipe for making the Yogurt-Tomato sauce portion. I am posting the gyros portion so that other chefs will know what the recipe had looked like in its entirety. DH and I made these for dinner two nights ago and thought they were very tasty. Prep time does not include overnight marinating of the pork tenderloin, nor the time it takes to make the yogurt-tomato sauce as Ice Cool Kitty gave an estimate for that in her recipe posting. While the original recipe says it makes 12 pitas, and that is how I am posting it, DH and I found it to make about 5 large pitas.
