01 - Whisk together olive oil, lemon juice, garlic, oregano, thyme, paprika, salt, and pepper in a large bowl. Add chicken tenders and toss thoroughly to coat. Cover and refrigerate for at least 30 minutes, up to 2 hours for deeper flavor penetration.
02 - Combine Greek yogurt, grated cucumber, dill, olive oil, lemon juice, garlic, salt, and pepper in a medium bowl. Mix until well incorporated. Refrigerate until serving time to allow flavors to meld.
03 - Heat grill or grill pan over medium-high setting. Lightly coat the 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 internal temperature reaches 165°F and attractive char marks develop.
05 - Arrange grilled chicken tenders on a serving platter. Accompany with chilled yogurt sauce, fresh lemon wedges, and a sprinkle of chopped herbs. Serve immediately while hot.
