01 - Whisk together olive oil, lemon juice, minced garlic, oregano, thyme, paprika, salt, and pepper in a large bowl. Add chicken tenders and toss until evenly coated. 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 thoroughly until smooth and well incorporated. Refrigerate until serving.
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. Grill tenders for 3-4 minutes per side until fully cooked through with internal temperature reaching 165°F and distinct char marks appear.
05 - Arrange grilled chicken tenders on a serving platter. Accompany with chilled yogurt sauce, fresh lemon wedges, and sprinkle with chopped parsley or dill. Serve immediately while hot.
