Cut biscuit dough into sixths and place in gallon size Ziploc bag with bread crumbs.
Shake until evenly coated.
In a large bowl, combine panko-coated biscuit dough, chicken, marinara sauce, mozzarella cheese, and Parmesan cheese and gently fold ingredients together.
Spoon into greased 9x13 inch pan.
Bake at 350 degrees approximately one hour, or until biscuits are baked through.
*Cover with foil after 45 minutes to prevent over-browning.
