I used to work at a pizza place that had the exact same recipe. I'm faily sure it was a coincidence, Here's what I can tell you. The dough is a regular fresh dough. the cheese is white colby. The sauce is made up of Conte pizza sauce,but since I never made it, i don't know what amouts of spices went in. I know the following were added, red pepper, garlic powder, rosemary, oregano, water, sugar and salt.

You roll out the dough. Heat the over to about 400. Put the cheese on first! Then add the sauce. Run a stripe of sauce around the edge, then put stripes across the middle about 1.5 inches apart. Bake it till it's glden and you're set.

Trust me, i worked at this place for 5 years, and when people realized that it was identical to Grotto, the business really took off.
