Crack the egg and let the egg white only drizzle into the gallon size Ziploc bag. Add the water. Seal and shake well.
Add chicken to bag. Seal, shake and squish the bag to coat the chicken with the egg white mixture.
Pour bread crumbs, grated parmesan cheese and garlic salt into a smaller zip loc bag. Seal and shake to incorporate well. Pour into the bag with the chicken. Seal, shake and squish the bag, pressing at different angles to ensure all chicken is coated well with breadcrumb mixture.
Dump chicken strips out of bag onto a foil-lined baking sheet. Brush or drizzle the top of each chicken breast with melted butter. Bake for 15 min. or until cooked through.
While baking, cut rolls in half lengthwise and place on clean counter cutting board.
When chicken is cooked, remove from oven. Place 2-3 chicken strips on each roll. Remove foil from baking sheet and place prepared rolls onto baking sheet. Pour a spoonful of sauce on top of each piece and sprinkle with fresh grated cheese.
Return to oven until sauce is cooked through and cheese is melted, about 2 min.
