Preheat oven to 400 degrees and line a baking pan with foil.
Make slits diagonally across your French bread about an inch to inch and a half apart.Cut down the bread but not all the way down so that it's still intact. Repeat the slicing this time going across.
Add a spoonful of sauce into each bread crevice (spoonful equal to about 2 teaspoons' worth). That should use up about a cup of sauce.
Insert one chicken tender in each bread crevice on top of the sauce.
Now add the rest of the 1/2 cup of sauce on top of the chicken pieces.
Spread 2 cups of shredded mozzarella cheese inside the bread crevices.
Combine your melted butter with garlic powder. brush on top of bread and on sides.
Bake on your foil-lined baking pan for about 10-15 minutes in a 400 degree preheated oven, or until cheese is bubbly and fully melted.
Sprinkle chopped parsley on top. Serve warm. So messy but worth it!
