01 - Whisk together olive oil, lemon juice, minced 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, chopped dill, olive oil, lemon juice, minced garlic, salt, and pepper in a medium bowl. Mix until smooth and refrigerate until serving time.
03 - Heat grill or grill pan to medium-high temperature. Lightly oil the grates 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 chicken reaches an internal temperature of 165°F and develops nice char marks.
05 - Arrange grilled chicken tenders on a serving platter. Accompany with chilled yogurt sauce, fresh lemon wedges, and sprinkle with chopped herbs.
