• Step 1: Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. Drain and rinse with cold water to stop the cooking process.
• Step 2: In a large mixing bowl, combine the cooked and cooled pasta, cherry tomatoes, bell pepper, cucumber, and red onion.
• Step 3: In a small bowl, whisk together the Italian dressing, red wine vinegar, dried oregano, and garlic powder. Season with salt and black pepper to taste.
• Step 4: Pour the dressing over the pasta and vegetables, and toss gently to coat everything evenly.
• Step 5: Cover the pasta salad and refrigerate for at least 30 minutes, or up to 4 hours, to allow the flavors to meld.
• Step 6: Just before serving, give the salad another gentle toss to ensure the dressing is evenly distributed. Adjust seasoning if necessary.
