01 - Combine olive oil, lemon juice, garlic, oregano, thyme, paprika, salt, and pepper in a large bowl. Add chicken tenders and toss to coat evenly. Cover and refrigerate for at least 30 minutes, up to 2 hours for deeper flavor penetration.
02 - While chicken marinates, mix Greek yogurt, grated cucumber, dill, olive oil, lemon juice, garlic, salt, and pepper in a medium bowl until well combined. Refrigerate until serving time.
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 nice char marks and internal temperature reaches 165°F.
05 - Arrange hot chicken tenders on a serving platter alongside the chilled yogurt sauce. Accompany with lemon wedges and sprinkle with fresh herbs.
