01 - In a large bowl, whisk together olive oil, lemon juice, minced garlic, dried oregano, thyme, smoked paprika, salt, and black pepper. Add chicken tenders and toss until evenly coated. Cover and refrigerate for at least 30 minutes, or up to 2 hours for deeper flavor penetration.
02 - While chicken marinates, combine Greek yogurt, grated and squeezed cucumber, chopped dill, olive oil, lemon juice, minced garlic, salt, and pepper in a medium bowl. Mix thoroughly and refrigerate until serving time.
03 - Heat grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
04 - Remove chicken from marinade, allowing excess to drip off. Place tenders on the preheated grill and cook for 3-4 minutes per side until fully cooked through with nice char marks and internal temperature reaches 165°F.
05 - Arrange hot chicken tenders on a serving platter. Accompany with chilled yogurt dipping sauce, fresh lemon wedges, and a sprinkle of chopped parsley or dill.
