Crush crackers. If using chicken breasts and not tenders, cut each chicken breast into 3 large pieces. Pour the milk, cheese and cracker crumbs into 3 separate small pans. Toss the salt and pepper into the cracker crumbs and stir the mixture around to combine. Dip each piece of chicken into the milk and then the cheese. Press the cheese into the chicken with your fingers. Then press the cheesy coated chicken into the cracker crumbs and press it in.
