Place a saucepan with water and 1/2 tbsp salt to boil. Pour the pasta and cook according to instructions on the package. Occasionally mixed, so as not to be bonded. During this time, heat the olive oil and when hot enough, put the garlic to fry until lightly browned. Then immediately add chopped zucchini rings and stew. When tender, add the fish (previously drained of excess fat) and fry for 1-2 minutes with constant stirring. Once ready topping is added to the hot, drained pasta of salt water. Sprinkle with chopped parsley and parmesan.
