Cook Pasta:
Bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and rinse with cold water to cool.
Prepare Vegetables:
While pasta cooks, chop cherry tomatoes, cucumber, bell peppers, red onion, and parsley. Slice olives and cube or shred mozzarella.
Make Dressing:
In a small bowl, whisk together olive oil, red wine vinegar, lemon juice, Dijon mustard, honey, oregano, garlic powder, salt, and pepper until well combined.
Combine Salad:
In a large bowl, combine cooked pasta, vegetables, olives, mozzarella, and parsley. Pour dressing over salad and toss gently to coat evenly.
Chill:
Cover and refrigerate for at least 1 hour to allow flavors to meld.
Serve:
Garnish with extra parsley or shredded cheese if desired. Serve chilled.
