Here's our better-for-you version of a gyro: BOCA Burgers with fat-free sour cream, garlic, plum tomatoes and crumbled feta cheese.
Heat grill to medium heat.
Grill burgers 8 minutes or until cooked through (160ºF), turning after 4 min.
Mix sour cream and garlic until blended.
Cut burgers in half. Top pitas with tomatoes, lettuce, cucumbers, sour cream sauce, burgers and feta; fold in half.
