Combine olive oil, lemon juice, garlic cloves, thyme, oregano, and
pepper in bowl. Place lamb strips in the marinade and coat well.
Cover and chill (4 to 6 hours or overnight) turning several times.
Meat can be grilled or baked in the oven on a rack (strips can be
threaded for skewers).
To make the gyro, place meat, lettuce, diced or thinly sliced tomato,
thinly sliced onion, and crumbled feta cheese in middle of pita
bread. Top with tzatziki (yogurt & cucumber sauce) and fold or wrap
pita around meat & vegetables.
Notes: Lamb meat should be from the leg or shoulder and sliced as
thin of strips as possible. You can also substitute beef for the lamb.
