Jan's Copycat Version of Pizza Hut®'s Stuffed Crust Pizza
Substitute olive oil for the shortening if desired.
Substitute 2 cups shredded cheese for the string cheese if desired.
If dough shrinks back when you try to stretch it in step 4, cover and let rest for 5 more minutes before trying again.
Bake pizzas at 400 degrees F (200 degrees C) until center is set and crust is crispy, about 30 minutes.
