Defrost rolls for about 2 hours until dough is completely thawed. Cut dough balls into two even pieces. Form into small pillow shapes, if desired. (I was too lazy to do that!)
Dissolve baking soda in hot water. Dip dough pieces into baking soda solution and place on greased baking sheet.
Brush dough with melted butter and more baking soda solution. Sprinkle salt, pepper, parsley flakes and parmesan cheese over top. Bake at 350 degrees for 12-15 minutes. Serve with mustard.
