Preheat the oven to 400 degrees F. Cook the rice until the 'al dente' stage as it will finish cooking in the oven. Allow to cool. Heat up 2 tablespoons olive oil in a saucepan. Add the pancetta, salami, and onions. Cook until golden and crispy. Cook the peas in a pot of salted water for approximately 2 minutes, or until soft. Add to the pan mixture and toss the ingredients together. Transfer the rice to a large bowl. Add an egg, Pecorino cheese, grated Parmigiano, diced Parmigiano, scamorza, salt, pepper, and the pancetta mixture with all its juices to the rice and thoroughly mix. Grease a baking dish with the remaining 2 tablespoons olive oil and sprinkle half the bread crumbs to the base of the pan. Spread the mixture onto the baking pan, packing the mixture so it serves as a solid bed. Sprinkle the remaining bread crumbs on top. Bake for 20 minutes or until the rice cake is golden.
