In a large bowl, add the zucchini, cucumber, red onion, tomatoes, and olives.
In a small food processor, add the sun-dried tomatoes, balsamic vinegar, lemon juice, garlic, and oregano. With the food processor running, slowly drizzle in the olive oil until dressing is smooth. Season with salt and pepper.
When ready to serve, drizzle the dressing over the salad and toss gently to coat. Sprinkle with goat cheese and sunflower seeds if wanted, and enjoy!
When spiralizing cucumber, place the "noodles" between several sheets of paper towels and press down to remove excess liquid. This will help prevent the salad from becoming watered down and soggy.
