Preheat your oven to 425 degrees.
Line a baking dish with foil to prevent sticking.
Prepare two small, flat bottomed bowls - one with the crushed cheez its and one for the ranch dressing.
Rinse chicken and pat dry.
Dip one piece of chicken into the ranch and spread with your fingers to coat.
Coat with crushed crackers and place on the foil lined tray. Repeat with the remaining chicken.
Bake in preheated oven for 30 minutes, or until crispy and golden, and juices run clear. Serve hot.
