As pasta is cooking, heat oil in a medium skillet. Add onion and garlic, saute until soft. Add zucchini and continue to saute over low heat until almost soft. Mix in tomatoes, cook for 30 seconds. Then add water, parsley and oregano. Stir well, cover and simmer for 5 minutes.
Remove from heat and add to pasta in a serving bowl. Sprinkle parmesan cheese on top and season with black pepper and salt. Mix well and serve hot.
This recipe is best complemented when served with Garlic French Bread.
