Preheat oven to 400 degrees F (205 degrees C). Coat a
baking sheet with a nonstick spray.
Cut chicken into finger-sized pieces.
In a bag, mix together flour, 1/2 teaspoon garlic
powder, 1/2 teaspoon cayenne pepper, and 1/4 teaspoon salt.
On a plate, mix the bread crumbs with the rest of the
garlic powder, cayenne pepper, and salt.
Shake the chicken pieces with the seasoned flour. Beat
egg whites with 1 tablespoon water, and place egg mixture
in a shallow dish or bowl. Dip seasoned chicken in egg
mixture, then roll in the seasoned bread crumb mixture. Place
on prepared baking sheet. Spray with nonstick spray.
Bake for about 8 minutes. Use tongs to turn pieces
over. Spray with nonstick spray. Bake 8 minutes longer, or until chicken is tender.
