Heat oil in a large saucepan over medium-high heat. Sauté the onion & garlic until the onion is soft, about 4 minutes. Add the stock and rice. Simmer over low heat, covered, about 10 minutes. Add zucchini. Season to taste with salt & pepper and simmer until the zucchini is tender, about 15 minutes. In a bowl beat the egg with the cheese and parsley, then whisk into the soup. Makes 4-6 servings.
