Preheat oven to temperature as directed on crescent roll packaging. Lightly grease a 12-inch pizza pan or baking sheet with cooking spray.
Unroll both cans of dough, separate along perforated lines into triangles. Overlap triangles at the widest point, with the narrow end pointing outward, to form a circle.
Sprinkle ½ cup of cheese evenly around the ring, then top with spoonfuls of sauce, spreading evenly into one layer. Top with pepperoni slices and remaining half cup of cheese.
Fold pointed end of each triangle over top of filling, tucking dough under the bottom layer to secure. Sprinkle top of dough with Italian seasoning and bake until dough is cooked through and golden brown, about 18-22 minutes. Cool slightly before slicing to serve.
Notes
Add some veggies for extra flavor! Great additions include fresh sliced mushrooms, chopped green bell peppers and chopped onions. You can also brown some ground italian sausage and add that.
