Bake chicken tenders as directed on package.
Cut each sub roll lengthwise on the top of the roll 3/4 way through the roll and place in a 9x13 baking dish.
Use 1/2 the cheese, placing it at the bottom of the cut in each roll.
Place one cooked chicken tender (or half if it is too big) into each sub roll.
Spoon marinara sauce over the top of each roll to cover the chicken and use the remaining cheese to cover the sauce.
Bake at 400F for 8-12 minutes or until the cheese is melted and the subs are hot throughout.
Serve hot whole, or cut into halves or thirds with the remaining marinara sauce for a dip.
Enjoy!
