In a mixing bowl, combine olive oil, minced garlic, oregano, lemon juice, salt, and pepper. Add the chicken tenders, ensuring they are fully coated in the marinade. Cover the bowl and let it marinate for at least 15 minutes at room temperature, or up to 2 hours in the refrigerator.

Heat a skillet over medium-high heat, add a tablespoon of olive oil once hot. Ensure the skillet is large enough for even cooking.

Add the marinated chicken tenders in a single layer and cook for about 4 to 5 minutes on one side. Flip and cook for another 4 to 5 minutes until the internal temperature reaches 165°F.

Remove the chicken tenders from the skillet and let them rest for about 2 minutes before serving.
