Place chicken slices in a saute pan over medium heat. Salt and pepper the chicken. Cook chicken until no longer pink. Layer chicken at the bottom of a greased 8x8 or 9x9 baking pan.
Combine soup and sour cream. Spread over chicken.
Crush the Goldfish crackers in a food chopper or plastic bag. Combine with melted butter. Sprinkle crumb mixture over the soup layer.
Bake at 350° for 30 minutes, or until bubbly. Enjoy!
