Visit http://www.ketomealsandrecipes.com/recipe/pork-gyro/ for the written recipe. Pork gyro is one of two most popular Greek street foods. The tenderloin is seasoned with traditional herbs and marinated to perfection. The preparation is easy with few steps. Served in my grain free pita and my Keto version of Tzatziki. This meal is one of the most satisfying, feel-good experiences on a keto and gluten-free diet.
