Preheat oven to 425 degrees F and grease a large baking dish.
Pound the chicken breasts into thin even pieces. This step is optional, but gives you more of that crispy outer edge.
In a large shallow bowl, mix together the crushed crackers, salt and seasoning of your choice.
Dip the chicken breasts into the melted butter, and then press into the cracker mixture, evenly coating them on all sides. Arrange the chicken into your prepared dish. If you have any extra melted butter left when you're done, you can evenly pour it into your dish.
Bake for 25-45 minutes or until the chicken is no longer pink with an internal temperature of 165 degrees F. The time will greatly depend on the size and thickness of your chicken. If you choose not to pound it, it may take longer.
