01 - Whisk together olive oil, lemon juice, minced garlic, oregano, thyme, smoked paprika, salt, and pepper in a large bowl until well combined.
02 - Add chicken tenders to the bowl and toss thoroughly to coat evenly with the marinade. Cover and refrigerate for at least 30 minutes, up to 2 hours for deeper flavor penetration.
03 - 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 internal temperature reaching 165°F and char marks appear.
06 - Arrange grilled chicken tenders on a platter alongside the chilled yogurt sauce. Garnish with lemon wedges and fresh herbs. Serve immediately while hot.
