01 - Whisk together olive oil, lemon juice, minced garlic, oregano, thyme, smoked 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 with excess moisture removed, chopped fresh dill, olive oil, lemon juice, minced garlic, salt, and pepper in a medium bowl. Mix until smooth and evenly incorporated. Refrigerate until serving time.
03 - Heat grill or grill pan to medium-high temperature. Lightly coat the grates with oil to prevent sticking.
04 - Remove chicken from marinade and allow excess liquid to drip off. Place tenders on the preheated grill and cook for 3-4 minutes on each side until internal temperature reaches 165°F and attractive char marks develop.
05 - Arrange hot chicken tenders on a serving platter alongside chilled yogurt dipping sauce. Accompany with lemon wedges and sprinkle generously with freshly chopped herbs.
