01 - Combine olive oil, lemon juice, minced garlic, dried oregano, thyme, smoked paprika, salt, and pepper in a large bowl. Add chicken tenders and toss thoroughly to coat. Cover and refrigerate for minimum 30 minutes, up to 2 hours for enhanced flavor.
02 - While chicken marinates, mix Greek yogurt, grated squeezed cucumber, chopped dill, olive oil, lemon juice, minced garlic, salt, and pepper in a medium bowl until well combined. Refrigerate until serving time.
03 - Heat grill or grill pan over medium-high setting. Lightly coat grill grates with oil to prevent sticking.
04 - Remove chicken from marinade, allowing excess to drip off. Place on preheated grill and cook for 3-4 minutes per side until fully cooked through with nice char marks. Internal temperature should reach 165°F.
05 - Arrange hot chicken tenders on serving platter alongside chilled yogurt sauce. Accompany with lemon wedges and sprinkle fresh parsley or dill over top.
