Process olive oil, red wine vinegar, 2 tablespoons fresh basil, green onion, Parmesan, salt, and pepper in a blender or food processor until smooth to create the dressing.

In a large bowl, combine cooked rotelle pasta, sliced bell pepper strips (red, green, and yellow), tomato wedges, black olives.

Pour the prepared dressing over the pasta mixture and toss to ensure even coating.

Roll mozzarella cheese cubes in the remaining 2 tablespoons of fresh basil to coat.

Add the basil-coated cheese cubes to the salad and sprinkle with dried oregano.

Toss the salad lightly to combine all ingredients.

Serve the Mediterranean pasta salad at room temperature.
