In a mixing bowl, combine the chicken breasts, minced garlic, dried oregano, olive oil, lemon juice, salt, and pepper. Ensure each piece of chicken is well-coated in the marinade. Allow the chicken to marinate at room temperature for at least 15 minutes, or up to 2 hours in the refrigerator for a more intense flavor infusion.

While the chicken marinates, place a cast iron skillet (or regular skillet) on the stove over medium-high heat. Preheat the pan for about 5 minutes until it is hot enough for a good sear.

Once the skillet is hot, carefully add the marinated chicken tenders in batches, ensuring not to overcrowd the pan. Sear each side for approximately 4-5 minutes until the chicken turns a beautiful golden brown color and is fully cooked through.

After cooking, remove the chicken tenders from the skillet and place them on a clean cutting board. Allow the chicken to rest for about 2 minutes.

Finally, slice the chicken into strips if desired and transfer to a serving platter. Pair with a crisp Greek salad, warm pita bread, or creamy tzatziki for a complete meal.
