2 1/2 pounds boneless skinless chicken breast, cut into 1-inch chunks
4 cloves garlic, finely chopped
1/2 teaspoon freshly ground black pepper
3 tablespoons extra-virgin olive oil, divided
3/4 teaspoon coarse sea salt, divided
1 lemon, juice and zest, divided
1 large cucumber, peeled and roughly chopped
1/4 pound (about 1 cup) crumbled feta cheese
1/3 cup finely diced red onion
1/4 cup finely chopped fresh parsley
In a large bowl, combine chicken, garlic, pepper, 2 tablespoons oil, 1/2 teaspoon salt and all but 1 tablespoon of lemon juice and toss to coat. Marinate at least 20 minutes or up to 8 hours.
Meanwhile, place cucumbers in a food processor and pulse until finely chopped but not pureed. Transfer to a bowl and stir in feta, onion, parsley, lemon zest, remaining 1 tablespoon lemon juice, remaining 1 tablespoon oil and remaining 1/4 teaspoon salt. Cover and refrigerate up to 8 hours; bring to room temperature before serving.
Prepare grill for medium-high-heat cooking. Thread chicken on metal (or well-soaked wood or bamboo) skewers and grill, turning frequently, until browned and cooked through, 6 to 8 minutes. Remove chicken from skewers, place on a platter and spoon feta-cucumber relish over top.
