Toss the zucchini, radishes, onion, green peppers, cauliflower, tomato, parsley, garlic, and basil together in a bowl. Sprinkle with the salad oil and lemon juice.
Dissolve the sugar and vinegar in a saucepan over medium heat. Pour over the salad. Season to taste with salt, pepper, onion or garlic powder, seasoned salt, and grated Parmesan cheese.
Chill several hours before serving, stirring occasionally to distribute the juices.
