In a food processor, spin the coconut with the flour and salt, if desired, and then place it in a shallow bowl. (Kids may prefer smaller pieces of coconut.) Otherwise, mix coconut, flour, and salt in a shallow bowl.
In another shallow bowl, combine eggs and water.
Dip chicken pieces in egg mixture, and then in coconut mixture, pressing to help it adhere.
Heat oil on medium-high in a large skillet. Cook chicken pieces for about 5 minutes, then flip and cook for another 5 minutes, until cooked through. If the outside of the chicken starts to burn, reduce the heat.
Serve with Copycat Chick-Fil-A Sauce
