Cut the chicken into finger-sized pieces.
Crush the chips with the back of a wooden spoon or a rolling pin into small pieces, like bread crumbs.
In medium bowl, beat the egg and milk. Dip the chicken pieces into the egg mixture, then put them in the bag and shake gently to coat. Place the chicken pieces on an ungreased cookie sheet and sprinkle with garlic powder.
Let sit for 10 minutes then bake for 20 minutes, flipping once.
