Grated cheese (Parmesan or Grana Padano), to taste
Breadcrumbs, as needed
Fine salt, to taste
1 egg
Instructions
Cook the rice in salted water until al dente.
Drain the rice and let it cool. Once cooled, transfer the rice to a bowl, add the cooked tomato sauce, and mix thoroughly.
Add the egg and 3 tablespoons of grated cheese. Continue to mix well.
Grease or prepare a baking dish and sprinkle the bottom with breadcrumbs. Pour in half of the rice mixture and smooth the surface evenly.
Add the diced mozzarella, cooked peas, and a generous handful of grated cheese over the layer of rice.
Cover with the remaining rice, level the surface, and sprinkle with a little more grated cheese.
Bake in a convection (fan-assisted) oven at 180°C (350°F) for 20 minutes, or in a conventional oven at 190°C (375°F) for the same amount of time. Once the surface is nicely golden brown, it is ready to serve!
