2 pounds chuck roast, sliced into 1/4" strips
1 teaspoon salt
1/2 teaspoon ground black pepper
2 cloves garlic, minced
3 tablespoons olive oil
Juice from 1 lemon
1 teaspoon dried oregano
1 teaspoon dried basil
4 - 6 white or whole wheat pitas
Lettuce leaves, for topping
Cherry tomatoes, halved, for topping
Red onion, thinly sliced, for topping
1 1/2 cups tzatziki sauce (store-bought or homemade), for topping
Place beef strips into the bottom of a 6-quart slow cooker and season generously with salt and pepper. Toss to distribute seasoning among meat. Sprinkle garlic on top.
In a small bowl combine the olive oil, lemon juice, oregano, and basil. Season with a pinch more salt and pepper. Pour over the meat and garlic and toss.
Place lid on slow cooker and cook on low for 7 - 8 hours or on high for 3 - 4 hours, until meat is tender.
When meat is ready, cut pita in half if they have a pocket. If they don't have a pocket, just lay the pita flat. Pile the meat into or onto the pita and top with lettuce, cherry tomatoes, red onion, and tzatziki sauce.
