Preparation

• Heat 1-1/2 Tbs. of the oil in a 12-inch skillet over medium heat. Add about three-quarters of the onion, 1/2 tsp. salt, and 1/8 tsp. pepper and cook, stirring occasionally, until golden-brown, 8 to 10 minutes. With a slotted spoon, transfer the onion to a small bowl; set aside.

  Cook the lamb, cinnamon, 3/4 tsp. salt, and 1/4 tsp. pepper in the skillet over medium-high heat, stirring occasionally and breaking up the meat, until cooked through, 5 to 7 minutes; drain well.

  Meanwhile, finely chop the remaining raw onion and transfer to a large bowl. Cut the peels and pith from the oranges. Working over a bowl to collect the juice, cut the orange segments free from the membranes. Cut the segments into chunks. Add the oranges, orange juice, cucumber, vinegar, mint, and the remaining 1 Tbs. oil to the chopped raw onion; toss to combine. Season to taste with salt and pepper.

  Fill the pitas with the lamb and cooked onions. Add some of the orange-cucumber salad and a dollop of yogurt. Serve the remaining salad on the side.
