Chicken Souvlaki

For the Chicken:

5 tablespoons fresh juice from about 3 lemons
4 tablespoons red wine vinegar
4 tablespoons olive oil
2 tablespoons chopped fresh oregano leaves
2 teaspoons kosher salt
1/2 teaspoon ground black pepper
2 pounds skinless boneless chicken breast, trimmed of excess fat and cut into 1-inch pieces
4 medium cloves garlic, grated (about 4 teaspoons)

To Serve

Tzatziki Sauce or Dill Dip

In a medium bowl, whisk lemon juice, vinegar, olive oil, oregano, salt, and black pepper. Place chicken cubes in a separate medium bowl. Mix in grated garlic and 7 tablespoons of dressing. Toss chicken to coat evenly, cover, and refrigerate to marinate for about 2 hours, tossing occasionally. You can use the remaining marinade for salad dressing.
Skewer chicken pieces on 8 to 12 skewers. Discard used marinade. Heat grill or grill pan over medium-high heat. Place chicken skewers on grill (or cook in batches on grill pan) until well browned and internal temperature registers 155°F (68°C) on an instant-read thermometer, turning evenly to cook on all sides, about 5 minutes total. (Adjust temperature of grill if necessary.) Remove chicken to a serving platter and let rest 3 minutes. Meanwhile, briefly grill pitas and keep warm.

Serve skewers with salad, pita, and tzatziki sauce. Remove chicken from skewers to stuff into pitas with sauce and Greek salad.
