10 mushrooms if canned, or 5 or 6 if fresh ones 3/4 of a cup of rice

Chop up a little onion, parsley, celery, and carrot together, and put them on the fire with two tablespoons of good olive−oil. When this sauce is colored, add two tablespoons of tomato paste, thinned with hot water (or a corresponding quantity of tomato sauce). Season with salt and pepper. Cut the mushrooms into small pieces, and add them to the sauce. Cook for twenty minutes over a medium fire. Put on one side and prepare the rice as follows:

Fry the rice with a lump of butter until dry; then add hot water, a little at a time, and boil gently. When the rice is half cooked (after about ten minutes) add the mushrooms and sauce, and cook for another ten minutes. If u want u can add grated Parmesan cheese before serving.
