In a mixing bowl, combine chicken tenders with olive oil, minced garlic, oregano, lemon juice, salt, and pepper. Stir well to coat the chicken evenly and marinate for 15 minutes.

Heat a cast-iron skillet over medium-high heat for 3-4 minutes. Add 1 tablespoon of olive oil and ensure it coats the bottom.

Add the marinated chicken tenders in a single layer. Cook for about 4-5 minutes per side until golden brown.

Check the internal temperature of the chicken; it should reach 165°F (75°C). Cook for an additional minute if necessary.

Transfer the chicken tenders to a serving platter and let them rest for about 2 minutes before serving.

Serve warm with a fresh salad, warm pita, tzatziki, or hummus.
