In a large mixing bowl, combine the cooked pasta, diced grilled chicken, halved cherry tomatoes, diced cucumber, diced bell peppers, and diced red onion. Use a spatula to gently fold the ingredients together until evenly distributed.

In a separate small bowl, whisk together ¼ cup of olive oil, the juice of one fresh lemon, ¼ cup of grated Parmesan cheese, and a pinch of salt and pepper until smooth and well-emulsified.

Drizzle the prepared dressing over the combined salad ingredients and toss gently to ensure all pieces are coated.

Sprinkle freshly chopped parsley over the top for added freshness and color.
