Lay frozen rolls out on parchment paper in one layer with a sprayed piece of saran wrap over the top for 45 minutes until soft enough to use palms of hands to press two together and flatten.
Spread some sauce on a roll, top with cheese and pepperoni slices. Top with another biscuit, sauce, cheese, pepperoni and repeat.
When you have a pile, line them up sideways in a loaf pan lined with parchment paper until they're all done and lined up in the pan.
Sprinkle with garlic salt and oregano on top. Add extra cheese on top of everything too.
Bake for about 30 minutes or until top is golden brown and take out.
