Preheat oven to 375°F. Lightly coat a large baking sheet with cooking spray and set aside.

Unroll dough and cut into 4 equal rectangles. Cut each rectangle lengthwise into 10 thin pieces, for a total of 40 strips of dough.
3
Wrap each meatball with 2 strips of dough to resemble bandages. Stretch the dough slightly as you are wrapping to completely cover the meatball. Separate some of the bandages at the top to create a hole for the "face" of the mummy.

Place mummies onto baking sheet and spray lightly with cooking spray. Bake for 15 minutes, or until dough is a light golden brown.
5
Dot mustard "eyes" on to the face of the mummy. Enjoy with marinara sauce, if desired.
