1. Heat oven to 425 degrees. Grease 13x9 inch pan. Unroll dough and press in bottom and 1 inch up sides of greased pan. Place pieces of string cheese along the inside edges of dough. Fold the 1 inch of dough over and around the cheese; press dough edges to seal. Top the crust with sauce, pepperoni and cheese. 2. Bake at 425 degrees for 15 to 18 minutes or until crust is golden brown and cheese is melted. Makes 6 servings. Typed by Lynn Thomas. Source: Pillsbury. Lynn's notes: I made this 1-11-97. It was easy to do and delicious. Next time I'll sprinkle some herbs on the edges of the crust to add more flavor to the dough. This hint comes from Terri Irwin: Wrap sticks of cheddar cheese in pepperoni and form the crust edges around it. I tried it and it was delicious!
