Prepare the Dressing: In a medium bowl, whisk together olive oil, red wine vinegar, lemon juice, honey, garlic, oregano, salt, pepper, and red pepper flakes. Let it sit to infuse the flavors while preparing the other ingredients.

Prepare the Vegetables: Wash and slice the cucumber, halve the cherry tomatoes, thinly slice the red onion, and chop the parsley.

Combine Pasta and Dressing: Transfer the warm pasta to a large mixing bowl and pour the dressing over it, tossing thoroughly to coat.

Add the Remaining Ingredients: Add cucumber, cherry tomatoes, olives, feta cheese, red onion, and parsley to the pasta. Gently toss to combine.

Adjust Seasoning and Serve: Taste and adjust the seasoning as needed. Chill for at least an hour before serving.
