Homemade spaghetti is made by kneading a dough of flour, eggs, and olive oil, then rolling and cutting it into thin strips. The pasta is boiled until tender, while a flavorful sauce is prepared using tomatoes, garlic, herbs, and optional vegetables. Once combined, the dish is garnished with parmesan and basil for a delicious touch. Serve hot with garlic bread or salad for a complete meal.
