In a covered dish, add chopped broccoli, cauliflower, tomatoes, olives, bell peppers, and carrot.
Drizzle all dressing ingredients over the tops of the vegetables, and shake around to mix well.
Refrigerate vegetables to marinate for at least an hour, up to overnight.
Spiralize the cucumber, and add 1/2 a cucumber to each plate. Sprinkle the cucumber "noodles" with parmesan cheese, and lightly season with sea salt and black pepper.
Divide the marinated veggies over the 4 plates of "pasta."
Garnish with more parmesan cheese, chopped parsley, and chopped walnuts or seeds.
If you don't have a spiralizer, try making veggie "peels" with a vegetable peeler. I have also heard of using a julienne peeler to make long veggie strands. Nothing is as fast and easy as using a spiralizer though!
