Bring a pot of water to boil. Season the water with a small palmful of sea salt and add in the pasta. Stir and follow the package directions for cooking times. Once the pasta is cooked, drain and rinse under cold water to stop the cooking. Drain well.
In a large mixing bowl, combine cooked pasta with halved cherry tomatoes, bell peppers, red onion, olives, feta, chopped spinach and fresh herbs.
Drizzle with some of the dressing, toss to combine and refrigerate until ready to serve.
Right before serving, toss with more dressing as desired. Taste and season with salt and pepper.
