With knife or pizza cutter, cut each rectangle lengthwise into 10 pieces, making a total of 40 pieces of dough.
Wrap 4 pieces of dough around each hot dog to look like "bandages," stretching dough slightly to completely cover hot dog.
About ½ inch from one end of each hot dog, separate dough so a piece of the hot dog shows through for face.
On an ungreased large cookie sheet, place wrapped hot dogs and spray dough lightly with cooking spray.
Bake for 13 to 17 minutes or until dough is light golden brown and hot dogs are hot.
With mustard, draw eyes and a mouth where the face goes.
Notes
Place leftover Mummy Dogs in an airtight container and refrigerate for up to two days. To reheat, place on ungreased cookie sheet and loosely cover with foil. Bake in the oven at 325°F for about 10 minutes or until heated through.
