Spray counter lightly with non-stick cooking spray. Roll combined rolls or loaf into a 16-inch circle. Cover with plastic wrap and let rest 10-15 minutes.
Remove wrap and place on a 14-inch sprayed pizza pan (edges will overlap pan). Cut each string cheese in half lengthwise and arrange, 1-inch in around the edge of the dough circle. Bring the edge of the dough over the cheese and press to seal it inside. Continue this around the entire circle. Press seams a second time to make sure they are fully sealed.
Top with sauce and your favorite pizza toppings. Bake at 400°F 10-20 minutes or until crust is golden brown.
