01 - In a large bowl, whisk together olive oil, lemon juice, minced garlic, dried oregano, thyme, smoked paprika, salt, and black pepper until well combined.
02 - Add chicken tenders to the marinade, tossing to coat thoroughly. Cover bowl and refrigerate for at least 30 minutes, up to 2 hours for enhanced flavor penetration.
03 - While chicken marinates, 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.
04 - Heat grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
05 - Remove chicken from marinade, allowing excess to drip off. Grill tenders for 3-4 minutes per side until fully cooked through with nice char marks and internal temperature reaches 165°F.
06 - 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.
