Preheat oven to 350F. Sprinkle chicken with salt, garlic salt, and white pepper; dredge with flour. Beat eggs with water. Dip chicken in egg mixture and roll to cover; then coat with ground peanuts, pressing lightly. Melt butter in a large skillet over medium-high heat. Add chicken; brown for 4 minutes on each side. Transfer to a shallow baking pan (if skillet handle is not oven-proof). Bake for 15 minutes.
