Cook the Pasta: Bring salted water to a boil and cook your pasta al dente (check package for time). Drain and rinse under cold water.
Prep the Ingredients: While pasta cooks, chop all your salad ingredients (cherry tomatoes, red onion, bell pepper, etc.).
Make the Dressing: In a bowl or jar, whisk together olive oil, red wine vinegar, garlic powder, Italian seasoning, and mustard. Season to taste.
Combine: In a large bowl, toss cooled pasta with the chopped veggies and olives. Pour over dressing and mix well.
Add Cheese & Herbs: Stir in feta cheese and fresh herbs. Adjust salt and pepper.
Chill & Serve: Refrigerate for at least 30 minutes. Garnish with extra herbs before serving.
