Gratin Rice

In a pot, heat two tablespoons of oil and sauté the rice. Add four cups of boiling water and one tablespoon of salt. Stir and let it cook over medium heat for about 15 minutes or until the rice has absorbed the water.

Remove the rice from the heat and cover the pot. Set aside.

In a skillet, heat a couple of tablespoons of oil. Once hot, sauté the chopped onion and garlic. When the onion becomes translucent, add the chopped spicy chorizo.

Add the cooked rice to the skillet mixture, stir well, and season with salt, pepper, and oregano to taste. Transfer the mixture to an oven-safe dish.

Cover the rice with a layer of tomato sauce, then add the sliced mozzarella, followed by the remaining tomato sauce.

Finish by arranging the sliced tomato on top, sprinkling oregano to taste, and adding the grated Parmesan cheese.

Preheat the oven to 200°C (390°F). Bake the dish for about 10 minutes, or until the surface is golden and the mozzarella is melted.
