Prepare the Chicken: Place the chicken breasts on a cutting board and pound them to an even thickness using a meat mallet or rolling pin.
Season: Rub the chicken with olive oil, then season both sides with garlic powder, onion powder, smoked paprika, salt, pepper, and dried oregano.
Preheat the Griddle: Heat a griddle pan or flat-top griddle over medium-high heat. Lightly grease with a little oil.
Cook: Place the chicken breasts on the hot griddle and cook for 4-5 minutes on each side until golden brown and cooked through (internal temperature of 165°F/75°C).
Rest & Serve: Remove from heat, squeeze fresh lemon juice over the chicken, and let it rest for 5 minutes before slicing. Serve hot with your favorite sides.
